Q DP problem:
The TRS P consists of the following rules:

AVERAGE(s(x0), y1) → IF(false, le(y1, 0), le(y1, s(0)), le(y1, s(s(0))), s(x0), y1)
IF(true, b1, b2, b3, x, y) → IF2(b1, b2, b3, x, y)
IF4(false, x, y) → AVERAGE(s(x), p(p(y)))
IF2(false, b2, b3, x, y) → IF3(b2, b3, x, y)

AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))

le(0, x0)

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule IF(true, b1, b2, b3, x, y) → IF2(b1, b2, b3, x, y) we obtained the following new rules:

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
AVERAGE(s(x0), y1) → IF(false, le(y1, 0), le(y1, s(0)), le(y1, s(s(0))), s(x0), y1)
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF(true, false, y_0, y_1, 0, s(z0)) → IF2(false, y_0, y_1, 0, s(z0))
IF(false, y0, y1, y2, s(x0), y4) → AVERAGE(x0, s(y4))
IF2(false, z0, z1, 0, s(z2)) → IF3(z0, z1, 0, s(z2))
AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule AVERAGE(s(x0), y1) → IF(false, le(y1, 0), le(y1, s(0)), le(y1, s(s(0))), s(x0), y1) we obtained the following new rules:

AVERAGE(s(x0), s(z4)) → IF(false, le(s(z4), 0), le(s(z4), s(0)), le(s(z4), s(s(0))), s(x0), s(z4))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF(true, false, y_0, y_1, 0, s(z0)) → IF2(false, y_0, y_1, 0, s(z0))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
AVERAGE(s(x0), s(z4)) → IF(false, false, le(z4, 0), le(s(z4), s(s(0))), s(x0), s(z4))
IF2(false, z0, z1, 0, s(z2)) → IF3(z0, z1, 0, s(z2))
IF(false, y0, y1, y2, s(x0), y4) → AVERAGE(x0, s(y4))
AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(x0), s(z4)) → IF(false, false, le(z4, 0), le(s(z4), s(s(0))), s(x0), s(z4)) at position [3] we obtained the following new rules:

AVERAGE(s(x0), s(z4)) → IF(false, false, le(z4, 0), le(z4, s(0)), s(x0), s(z4))

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, le(s(z3), 0), le(s(z3), s(0)), s(x0), s(s(z3)))
IF(true, false, y_0, y_1, 0, s(z0)) → IF2(false, y_0, y_1, 0, s(z0))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF2(false, z0, z1, 0, s(z2)) → IF3(z0, z1, 0, s(z2))
AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4))
IF(false, false, y_0, y_1, s(z0), s(z1)) → AVERAGE(z0, s(s(z1)))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(x0), s(s(z3))) → IF(false, false, le(s(z3), 0), le(s(z3), s(0)), s(x0), s(s(z3))) at position [2] we obtained the following new rules:

AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(s(z3), s(0)), s(x0), s(s(z3)))

AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))

AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))

IF(false, false, y_0, y_1, s(z0), s(z1)) → AVERAGE(z0, s(s(z1)))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule IF(false, false, y_0, y_1, s(z0), s(z1)) → AVERAGE(z0, s(s(z1))) we obtained the following new rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF(true, false, y_0, y_1, 0, s(z0)) → IF2(false, y_0, y_1, 0, s(z0))
IF2(false, false, x1, 0, s(x2)) → IF3(false, x1, 0, s(x2))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF(true, false, y_0, y_1, 0, s(z0)) → IF2(false, y_0, y_1, 0, s(z0)) we obtained the following new rules:

IF(true, false, false, x1, 0, s(x2)) → IF2(false, false, x1, 0, s(x2))

IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF2(false, false, x1, 0, s(x2)) → IF3(false, x1, 0, s(x2))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(true, false, false, x1, 0, s(x2)) → IF2(false, false, x1, 0, s(x2))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))

AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule AVERAGE(0, s(z4)) → IF(true, false, le(z4, 0), le(z4, s(0)), 0, s(z4)) at position [2] we obtained the following new rules:

AVERAGE(0, s(0)) → IF(true, false, true, le(0, s(0)), 0, s(0))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(s(x0), s(0)), 0, s(s(x0)))

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF2(false, false, x1, 0, s(x2)) → IF3(false, x1, 0, s(x2))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
AVERAGE(0, s(0)) → IF(true, false, true, le(0, s(0)), 0, s(0))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(s(x0), s(0)), 0, s(s(x0)))
IF(true, false, false, x1, 0, s(x2)) → IF2(false, false, x1, 0, s(x2))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 1 SCC with 1 less node.

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(s(x0), s(0)), 0, s(s(x0)))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF2(false, false, x1, 0, s(x2)) → IF3(false, x1, 0, s(x2))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(true, false, false, x1, 0, s(x2)) → IF2(false, false, x1, 0, s(x2))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(0, s(s(x0))) → IF(true, false, false, le(s(x0), s(0)), 0, s(s(x0))) at position [3] we obtained the following new rules:

AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
IF2(false, false, x1, 0, s(x2)) → IF3(false, x1, 0, s(x2))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule IF2(false, false, x1, 0, s(x2)) → IF3(false, x1, 0, s(x2)) we obtained the following new rules:

IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))

Q DP problem:
The TRS P consists of the following rules:

IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2))
IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))

The TRS R consists of the following rules:

p(s(x)) → x
p(0) → 0
le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule IF3(false, z1, 0, s(z2)) → IF4(z1, 0, s(z2)) we obtained the following new rules:

IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1)))

By instantiating [15] the rule IF4(false, 0, s(z1)) → AVERAGE(s(0), p(z1)) we obtained the following new rules:

IF4(false, 0, s(s(z1))) → AVERAGE(s(0), p(s(z1)))

Q DP problem:
The TRS P consists of the following rules:

IF4(false, 0, s(s(z1))) → AVERAGE(s(0), p(s(z1)))
IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1)))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)
p(s(x)) → x

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule IF4(false, 0, s(s(z1))) → AVERAGE(s(0), p(s(z1))) at position [1] we obtained the following new rules:

IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)
p(s(x)) → x

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1)))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

p(s(x0))
p(0)
le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
We deleted the following terms from Q as each root-symbol of these terms does neither occur in P nor in R.

p(s(x0))
p(0)

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF(false, y_0, y_1, y_2, s(0), z0) → AVERAGE(0, s(z0)) we obtained the following new rules:

IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1)))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF3(false, z0, 0, s(s(z1))) → IF4(z0, 0, s(s(z1))) we obtained the following new rules:

IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF2(false, false, z0, 0, s(s(z1))) → IF3(false, z0, 0, s(s(z1))) we obtained the following new rules:

IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF(true, false, false, y_0, 0, s(s(z0))) → IF2(false, false, y_0, 0, s(s(z0))) we obtained the following new rules:

IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule AVERAGE(0, s(s(x0))) → IF(true, false, false, le(x0, 0), 0, s(s(x0))) at position [3] we obtained the following new rules:

AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(0, s(s(0))) → IF(true, false, false, true, 0, s(s(0)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)
AVERAGE(0, s(s(0))) → IF(true, false, false, true, 0, s(s(0)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 1 SCC with 1 less node.

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0)
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule AVERAGE(s(0), y_0) → IF(false, le(y_0, 0), le(y_0, s(0)), le(y_0, s(s(0))), s(0), y_0) we obtained the following new rules:

AVERAGE(s(0), s(y_4)) → IF(false, le(s(y_4), 0), le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4))
AVERAGE(s(0), s(s(y_5))) → IF(false, le(s(s(y_5)), 0), le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(y_4)) → IF(false, le(s(y_4), 0), le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
AVERAGE(s(0), s(s(y_5))) → IF(false, le(s(s(y_5)), 0), le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(y_4)) → IF(false, le(s(y_4), 0), le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4)) at position [1] we obtained the following new rules:

AVERAGE(s(0), s(y_4)) → IF(false, false, le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
AVERAGE(s(0), s(y_4)) → IF(false, false, le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
AVERAGE(s(0), s(s(y_5))) → IF(false, le(s(s(y_5)), 0), le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_5))) → IF(false, le(s(s(y_5)), 0), le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5))) at position [1] we obtained the following new rules:

AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(0), s(y_4)) → IF(false, false, le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(y_4)) → IF(false, false, le(s(y_4), s(0)), le(s(y_4), s(s(0))), s(0), s(y_4)) at position [2] we obtained the following new rules:

AVERAGE(s(0), s(y_4)) → IF(false, false, le(y_4, 0), le(s(y_4), s(s(0))), s(0), s(y_4))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(s(0), s(y_4)) → IF(false, false, le(y_4, 0), le(s(y_4), s(s(0))), s(0), s(y_4))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(s(y_5)), s(0)), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5))) at position [2] we obtained the following new rules:

AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(y_5), 0), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(s(0), s(y_4)) → IF(false, false, le(y_4, 0), le(s(y_4), s(s(0))), s(0), s(y_4))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)
AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(y_5), 0), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(y_4)) → IF(false, false, le(y_4, 0), le(s(y_4), s(s(0))), s(0), s(y_4)) at position [3] we obtained the following new rules:

AVERAGE(s(0), s(y_4)) → IF(false, false, le(y_4, 0), le(y_4, s(0)), s(0), s(y_4))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)
AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(y_5), 0), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_5))) → IF(false, false, le(s(y_5), 0), le(s(s(y_5)), s(s(0))), s(0), s(s(y_5))) at position [2] we obtained the following new rules:

AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(s(s(y_5)), s(s(0))), s(0), s(s(y_5)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(s(s(y_5)), s(s(0))), s(0), s(s(y_5))) at position [3] we obtained the following new rules:

AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(s(y_5), s(0)), s(0), s(s(y_5)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(s(y_5), s(0)), s(0), s(s(y_5)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(s(y_5), s(0)), s(0), s(s(y_5))) at position [3] we obtained the following new rules:

AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule IF(false, x0, x1, x2, s(0), s(y_0)) → AVERAGE(0, s(s(y_0))) we obtained the following new rules:

IF(false, false, y_0, y_1, s(0), s(z0)) → AVERAGE(0, s(s(z0)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1)
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF4(false, 0, s(s(z1))) → AVERAGE(s(0), z1) we obtained the following new rules:

IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))

Q DP problem:
The TRS P consists of the following rules:

IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3)))
AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF(false, false, y_1, y_2, s(0), s(x3)) → AVERAGE(0, s(s(x3))) we obtained the following new rules:

IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0))))

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0))))
IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF(false, false, false, y_0, s(z0), s(s(z1))) → AVERAGE(z0, s(s(s(z1)))) we obtained the following new rules:

IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF(false, false, false, x0, s(0), s(s(x2))) → AVERAGE(0, s(s(s(x2))))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0))))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))
IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule AVERAGE(s(0), s(x1)) → IF(false, false, le(x1, 0), le(x1, s(0)), s(0), s(x1)) we obtained the following new rules:

AVERAGE(s(0), s(s(y_4))) → IF(false, false, le(s(y_4), 0), le(s(y_4), s(0)), s(0), s(s(y_4)))

Q DP problem:
The TRS P consists of the following rules:

IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(0), s(s(y_4))) → IF(false, false, le(s(y_4), 0), le(s(y_4), s(0)), s(0), s(s(y_4)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0))))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))
IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_4))) → IF(false, false, le(s(y_4), 0), le(s(y_4), s(0)), s(0), s(s(y_4))) at position [2] we obtained the following new rules:

AVERAGE(s(0), s(s(y_4))) → IF(false, false, false, le(s(y_4), s(0)), s(0), s(s(y_4)))

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(s(0), s(s(y_4))) → IF(false, false, false, le(s(y_4), s(0)), s(0), s(s(y_4)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0))))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))
IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false
le(s(x), s(y)) → le(x, y)

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule AVERAGE(s(0), s(s(y_4))) → IF(false, false, false, le(s(y_4), s(0)), s(0), s(s(y_4))) at position [3] we obtained the following new rules:

AVERAGE(s(0), s(s(y_4))) → IF(false, false, false, le(y_4, 0), s(0), s(s(y_4)))

IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0))))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule IF(false, false, x0, x1, s(0), s(s(y_0))) → AVERAGE(0, s(s(s(y_0)))) we obtained the following new rules:

IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3)))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))
IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule AVERAGE(s(x0), s(s(z3))) → IF(false, false, false, le(z3, 0), s(x0), s(s(z3))) we obtained the following new rules:

AVERAGE(s(s(y_4)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(y_4)), s(s(x1)))
AVERAGE(s(s(0)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(0)), s(s(x1)))
AVERAGE(s(0), s(s(x1))) → IF(false, false, false, le(x1, 0), s(0), s(s(x1)))

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
AVERAGE(s(s(0)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(0)), s(s(x1)))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))
IF(false, false, false, x0, s(s(0)), s(s(x2))) → AVERAGE(s(0), s(s(s(x2))))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(s(y_4)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(y_4)), s(s(x1)))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 2 SCCs with 1 less node.

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule IF4(false, 0, s(s(s(y_0)))) → AVERAGE(s(0), s(y_0)) we obtained the following new rules:

IF4(false, 0, s(s(s(s(y_0))))) → AVERAGE(s(0), s(s(y_0)))

Q DP problem:
The TRS P consists of the following rules:

IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))
IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].

The following pairs can be oriented strictly and are deleted.

IF4(false, 0, s(s(s(s(y_1))))) → AVERAGE(s(0), s(s(y_1)))

The remaining pairs can at least be oriented weakly.

IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))

Used ordering: Polynomial interpretation [25]:

POL(0) = 0
POL(AVERAGE(x₁, x₂)) = x₁ + x₂
POL(IF(x₁, x₂, x₃, x₄, x₅, x₆)) = x₁ + x₆
POL(IF2(x₁, x₂, x₃, x₄, x₅)) = x₅
POL(IF3(x₁, x₂, x₃, x₄)) = x₄
POL(IF4(x₁, x₂, x₃)) = x₃
POL(false) = 1
POL(le(x₁, x₂)) = 0
POL(s(x₁)) = 1 + x₁
POL(true) = 0

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(0, s(s(s(x0)))) → IF(true, false, false, false, 0, s(s(s(x0))))
IF2(false, false, false, 0, s(s(x1))) → IF3(false, false, 0, s(s(x1)))
IF(true, false, false, false, 0, s(s(x1))) → IF2(false, false, false, 0, s(s(x1)))
IF3(false, false, 0, s(s(x1))) → IF4(false, 0, s(s(x1)))
IF(false, false, false, y_0, s(0), s(s(z1))) → AVERAGE(0, s(s(s(z1))))
AVERAGE(s(0), s(s(y_5))) → IF(false, false, false, le(y_5, 0), s(0), s(s(y_5)))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 0 SCCs with 6 less nodes.

Q DP problem:
The TRS P consists of the following rules:

AVERAGE(s(s(y_4)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(y_4)), s(s(x1)))
AVERAGE(s(s(0)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(0)), s(s(x1)))
IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))

The TRS R consists of the following rules:

le(0, y) → true
le(s(x), 0) → false

The set Q consists of the following terms:

le(0, x0)
le(s(x0), 0)
le(s(x0), s(x1))

We have to consider all minimal (P,Q,R)-chains.
By using the subterm criterion [20] together with the size-change analysis [32] we have proven that there are no infinite chains for this DP problem.

From the DPs we obtained the following set of size-change graphs:

IF(false, false, false, x0, s(s(y_0)), s(s(x2))) → AVERAGE(s(y_0), s(s(s(x2))))
The graph contains the following edges 5 > 1
AVERAGE(s(s(y_4)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(y_4)), s(s(x1)))
The graph contains the following edges 1 >= 5, 2 >= 6
AVERAGE(s(s(0)), s(s(x1))) → IF(false, false, false, le(x1, 0), s(s(0)), s(s(x1)))
The graph contains the following edges 1 >= 5, 2 >= 6
