The TRS R consists of the following rules:

p(s(x)) → x

The set Q consists of the following terms:

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule COND2(true, y0, 0, x0) → COND2(false, p(y0), p(0), x0) at position [2] we obtained the following new rules:

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

COND2(true, y0, s(x0), 0) → COND2(true, p(y0), x0, 0)
COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
COND1(true, y0, 0, x0) → COND2(false, y0, 0, x0)
COND2(false, s(x0), s(x1), y2) → COND1(and(eq(x0, x1), gr(s(x0), y2)), s(x0), s(x1), y2)
COND1(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), y0, s(x0), s(x1))
COND2(false, s(x0), y1, s(x1)) → COND1(and(eq(s(x0), y1), gr(x0, x1)), s(x0), y1, s(x1))
COND2(true, y0, 0, x0) → COND2(false, p(y0), 0, x0)
COND1(true, y0, s(x0), 0) → COND2(true, y0, s(x0), 0)

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule COND2(true, y0, 0, x0) → COND2(false, p(y0), 0, x0) at position [1] we obtained the following new rules:

COND2(true, s(x0), 0, y1) → COND2(false, x0, 0, y1)
COND2(true, 0, 0, y1) → COND2(false, 0, 0, y1)

COND2(true, s(x0), 0, y1) → COND2(false, x0, 0, y1)
COND1(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), y0, s(x0), s(x1))
COND2(false, s(x0), y1, s(x1)) → COND1(and(eq(s(x0), y1), gr(x0, x1)), s(x0), y1, s(x1))
COND1(true, y0, s(x0), 0) → COND2(true, y0, s(x0), 0)

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule COND2(false, s(x0), s(x1), y2) → COND1(and(eq(x0, x1), gr(s(x0), y2)), s(x0), s(x1), y2) we obtained the following new rules:

COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(s(x0), s(z2))), s(x0), s(z1), s(z2))

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

COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(s(x0), s(z2))), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

The set Q consists of the following terms:

We have to consider all minimal (P,Q,R)-chains.

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
COND1(true, y0, 0, x0) → COND2(false, y0, 0, x0)
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))
COND2(false, s(x0), y1, s(x1)) → COND1(and(eq(s(x0), y1), gr(x0, x1)), s(x0), y1, s(x1))
COND2(true, s(x0), 0, s(z2)) → COND2(false, x0, 0, s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule COND1(true, y0, 0, x0) → COND2(false, y0, 0, x0) we obtained the following new rules:

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))

p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By forward instantiating [14] the rule COND2(false, s(x0), y1, s(x1)) → COND1(and(eq(s(x0), y1), gr(x0, x1)), s(x0), y1, s(x1)) we obtained the following new rules:

COND2(false, s(x0), s(y_2), s(x2)) → COND1(and(eq(s(x0), s(y_2)), gr(x0, x2)), s(x0), s(y_2), s(x2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(eq(s(x0), 0), gr(x0, x2)), s(x0), 0, s(x2))

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), s(y_2), s(x2)) → COND1(and(eq(s(x0), s(y_2)), gr(x0, x2)), s(x0), s(y_2), s(x2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(eq(s(x0), 0), gr(x0, x2)), s(x0), 0, s(x2))
COND2(true, s(x0), 0, s(z2)) → COND2(false, x0, 0, s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

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:

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(eq(s(x0), 0), gr(x0, x2)), s(x0), 0, s(x2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

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.

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

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(eq(s(x0), 0), gr(x0, x2)), s(x0), 0, s(x2))

The TRS R consists of the following rules:

eq(s(x), 0) → false
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule COND2(false, s(x0), 0, s(x2)) → COND1(and(eq(s(x0), 0), gr(x0, x2)), s(x0), 0, s(x2)) at position [0,0] we obtained the following new rules:

COND2(false, s(x0), 0, s(x2)) → COND1(and(false, gr(x0, x2)), s(x0), 0, s(x2))

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

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(false, gr(x0, x2)), s(x0), 0, s(x2))

The TRS R consists of the following rules:

eq(s(x), 0) → false
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

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

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(false, gr(x0, x2)), s(x0), 0, s(x2))

The TRS R consists of the following rules:

gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

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.

eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))

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

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(and(false, gr(x0, x2)), s(x0), 0, s(x2))

The TRS R consists of the following rules:

gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule COND2(false, s(x0), 0, s(x2)) → COND1(and(false, gr(x0, x2)), s(x0), 0, s(x2)) at position [0] we obtained the following new rules:

COND2(false, s(x0), 0, s(x2)) → COND1(false, s(x0), 0, s(x2))

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

COND1(true, s(z0), 0, s(z2)) → COND2(false, s(z0), 0, s(z2))
COND2(false, s(x0), 0, s(x2)) → COND1(false, s(x0), 0, s(x2))

The TRS R consists of the following rules:

gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 0 SCCs with 2 less nodes.

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
COND2(false, s(x0), s(y_2), s(x2)) → COND1(and(eq(s(x0), s(y_2)), gr(x0, x2)), s(x0), s(y_2), s(x2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule COND2(false, s(x0), s(y_2), s(x2)) → COND1(and(eq(s(x0), s(y_2)), gr(x0, x2)), s(x0), s(y_2), s(x2)) at position [0,0] we obtained the following new rules:

COND2(false, s(x0), s(y_2), s(x2)) → COND1(and(eq(x0, y_2), gr(x0, x2)), s(x0), s(y_2), s(x2))

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

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.


COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
The remaining pairs can at least be oriented weakly.

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))
Used ordering: Combined order from the following AFS and order.
COND1(x1, x2, x3, x4)  =  COND1(x1, x2, x3, x4)
true  =  true
s(x1)  =  s(x1)
COND2(x1, x2, x3, x4)  =  COND2(x1, x2, x3, x4)
gr(x1, x2)  =  gr
p(x1)  =  x1
false  =  false
and(x1, x2)  =  and
eq(x1, x2)  =  eq(x1, x2)
0  =  0

Recursive path order with status [2].
Quasi-Precedence:
[COND14, COND24] > eq2 > [true, gr, false, and, 0] > s1

Status:
COND24: [1,4,2,3]
gr: []
eq2: multiset
true: multiset
false: multiset
s1: multiset
and: []
0: multiset
COND14: [1,4,2,3]


The following usable rules [17] were oriented:

p(s(x)) → x
p(0) → 0
gr(0, x) → false
gr(s(x), 0) → true
and(false, x) → false
and(x, false) → false
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))

p(s(x0))

eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

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(0)
p(s(x0))

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
The DP Problem is simplified using the Induction Calculus [18] with the following steps:
Note that final constraints are written in bold face.


For Pair COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2)) the following chains were created:




For Pair COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2)) the following chains were created:




To summarize, we get the following constraints P for the following pairs.



The constraints for P> respective Pbound are constructed from P where we just replace every occurence of "t ≥ s" in P by "t > s" respective "t ≥ c". Here c stands for the fresh constant used for Pbound.
Using the following integer polynomial ordering the resulting constraints can be solved
Polynomial interpretation [18]:

POL(0) = 0   
POL(COND1(x1, x2, x3, x4)) = -1 - x1 + x3 - x4   
POL(COND2(x1, x2, x3, x4)) = 1 - x1 - x3 + x4   
POL(and(x1, x2)) = 0   
POL(c) = -1   
POL(eq(x1, x2)) = 0   
POL(false) = 1   
POL(gr(x1, x2)) = 0   
POL(s(x1)) = 1 + x1   
POL(true) = 0   

The following pairs are in P>:

COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))
The following pairs are in Pbound:

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))
The following rules are usable:

truegr(s(x), 0)
gr(x, y) → gr(s(x), s(y))
falsegr(0, x)
falseand(x, false)
trueand(true, true)
falseand(false, x)

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 0 SCCs with 1 less node.
We use the reduction pair processor [15].


The following pairs can be oriented strictly and are deleted.


COND2(true, y0, s(x0), s(x1)) → COND2(gr(x0, x1), p(y0), x0, s(x1))
The remaining pairs can at least be oriented weakly.

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))
Used ordering: Polynomial interpretation [25]:

POL(0) = 0   
POL(COND1(x1, x2, x3, x4)) = 1 + x2 + x3 + x4   
POL(COND2(x1, x2, x3, x4)) = x1 + x2 + x3 + x4   
POL(and(x1, x2)) = 0   
POL(eq(x1, x2)) = 0   
POL(false) = 1   
POL(gr(x1, x2)) = 1   
POL(p(x1)) = x1   
POL(s(x1)) = 1 + x1   
POL(true) = 1   

The following usable rules [17] were oriented:

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

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

COND1(true, s(z0), s(x1), s(z2)) → COND2(gr(x1, z2), s(z0), s(x1), s(z2))
COND2(false, s(x0), s(z1), s(z2)) → COND1(and(eq(x0, z1), gr(x0, z2)), s(x0), s(z1), s(z2))

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.

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

COND2(true, y0, s(x0), 0) → COND2(true, p(y0), x0, 0)

The TRS R consists of the following rules:

eq(0, 0) → true
eq(s(x), 0) → false
eq(0, s(x)) → false
eq(s(x), s(y)) → eq(x, y)
gr(0, x) → false
gr(s(x), 0) → true
gr(s(x), s(y)) → gr(x, y)
and(true, true) → true
and(false, x) → false
and(x, false) → false
p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.

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

COND2(true, y0, s(x0), 0) → COND2(true, p(y0), x0, 0)

The TRS R consists of the following rules:

p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
p(0)
p(s(x0))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

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.

gr(0, x0)
gr(s(x0), 0)
gr(s(x0), s(x1))
eq(0, 0)
eq(s(x0), 0)
eq(0, s(x0))
eq(s(x0), s(x1))
and(true, true)
and(false, x0)
and(x0, false)

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

COND2(true, y0, s(x0), 0) → COND2(true, p(y0), x0, 0)

The TRS R consists of the following rules:

p(0) → 0
p(s(x)) → x

The set Q consists of the following terms:

p(0)
p(s(x0))

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:
