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

IF1(store, m, false) → IF3(store, m, empty(fstsplit(m, store)))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), empty(cons(x1, fstsplit(x0, x2))))
IF2(store, m, false) → PROCESS(sndsplit(m, store), m)
PROCESS(store, m) → IF1(store, m, leq(m, length(store)))
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)

The TRS R consists of the following rules:

sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)
fstsplit(0, x) → nil
fstsplit(s(n), nil) → nil
fstsplit(s(n), cons(h, t)) → cons(h, fstsplit(n, t))
empty(nil) → true
empty(cons(h, t)) → false
length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), 0) → false
leq(s(n), s(m)) → leq(n, m)

The set Q consists of the following terms:

fstsplit(0, x0)
fstsplit(s(x0), nil)
fstsplit(s(x0), cons(x1, x2))
sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
empty(nil)
empty(cons(x0, x1))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), empty(cons(x1, fstsplit(x0, x2)))) at position [2] we obtained the following new rules:

IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF1(store, m, false) → IF3(store, m, empty(fstsplit(m, store)))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF2(store, m, false) → PROCESS(sndsplit(m, store), m)
PROCESS(nil, y1) → IF1(nil, y1, leq(y1, 0))
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)

The TRS R consists of the following rules:

sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)
fstsplit(0, x) → nil
fstsplit(s(n), nil) → nil
fstsplit(s(n), cons(h, t)) → cons(h, fstsplit(n, t))
empty(nil) → true
empty(cons(h, t)) → false
length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), 0) → false
leq(s(n), s(m)) → leq(n, m)

The set Q consists of the following terms:

fstsplit(0, x0)
fstsplit(s(x0), nil)
fstsplit(s(x0), cons(x1, x2))
sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
empty(nil)
empty(cons(x0, x1))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule IF1(store, m, false) → IF3(store, m, empty(fstsplit(m, store))) at position [2] we obtained the following new rules:

IF1(nil, s(x0), false) → IF3(nil, s(x0), empty(nil))
IF1(x0, 0, false) → IF3(x0, 0, empty(nil))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), empty(cons(x1, fstsplit(x0, x2))))

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF2(store, m, false) → PROCESS(sndsplit(m, store), m)
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), empty(cons(x1, fstsplit(x0, x2))))

The TRS R consists of the following rules:

fstsplit(0, x) → nil
fstsplit(s(n), nil) → nil
fstsplit(s(n), cons(h, t)) → cons(h, fstsplit(n, t))
empty(cons(h, t)) → false
length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

fstsplit(0, x0)
fstsplit(s(x0), nil)
fstsplit(s(x0), cons(x1, x2))
sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
empty(nil)
empty(cons(x0, x1))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), empty(cons(x1, fstsplit(x0, x2)))) at position [2] we obtained the following new rules:

IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF2(store, m, false) → PROCESS(sndsplit(m, store), m)
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

fstsplit(0, x0)
fstsplit(s(x0), nil)
fstsplit(s(x0), cons(x1, x2))
sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
empty(nil)
empty(cons(x0, x1))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, 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.

fstsplit(0, x0)
fstsplit(s(x0), nil)
fstsplit(s(x0), cons(x1, x2))
empty(nil)
empty(cons(x0, x1))

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF2(store, m, false) → PROCESS(sndsplit(m, store), m)
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule IF2(store, m, false) → PROCESS(sndsplit(m, store), m) at position [0] we obtained the following new rules:

IF2(x0, 0, false) → PROCESS(x0, 0)
IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF2(nil, s(x0), false) → PROCESS(nil, s(x0))

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF2(nil, s(x0), false) → PROCESS(nil, s(x0))
IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF2(x0, 0, false) → PROCESS(x0, 0)
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

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

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF3(store, m, false) → PROCESS(sndsplit(m, store), m)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By narrowing [15] the rule IF3(store, m, false) → PROCESS(sndsplit(m, store), m) at position [0] we obtained the following new rules:

IF3(nil, s(x0), false) → PROCESS(nil, s(x0))
IF3(x0, 0, false) → PROCESS(x0, 0)
IF3(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))

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

IF3(nil, s(x0), false) → PROCESS(nil, s(x0))
PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF3(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)
IF3(x0, 0, false) → PROCESS(x0, 0)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

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

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

PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1))))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF3(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By instantiating [15] the rule PROCESS(cons(x0, x1), y1) → IF1(cons(x0, x1), y1, leq(y1, s(length(x1)))) we obtained the following new rules:

PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(s(z2), s(length(x1))))

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

IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF3(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(s(z2), s(length(x1))))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
By rewriting [15] the rule PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(s(z2), s(length(x1)))) at position [2] we obtained the following new rules:

PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(z2, length(x1)))

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

IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF3(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(z2, length(x1)))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, 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.

IF2(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))
IF3(cons(x1, x2), s(x0), false) → PROCESS(sndsplit(x0, x2), s(x0))

The remaining pairs can at least be oriented weakly.

IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(z2, length(x1)))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)

Used ordering: Polynomial interpretation [25]:

POL(0) = 0
POL(IF1(x₁, x₂, x₃)) = x₁
POL(IF2(x₁, x₂, x₃)) = x₁
POL(IF3(x₁, x₂, x₃)) = x₁
POL(PROCESS(x₁, x₂)) = x₁
POL(cons(x₁, x₂)) = 1 + x₁ + x₂
POL(false) = 0
POL(length(x₁)) = x₁
POL(leq(x₁, x₂)) = 0
POL(nil) = 0
POL(s(x₁)) = 0
POL(sndsplit(x₁, x₂)) = x₂
POL(true) = 0

The following usable rules [17] were oriented:

sndsplit(s(n), nil) → nil
sndsplit(0, x) → x
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

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

IF1(cons(x1, x2), s(x0), false) → IF3(cons(x1, x2), s(x0), false)
PROCESS(cons(x0, x1), s(z2)) → IF1(cons(x0, x1), s(z2), leq(z2, length(x1)))
IF1(cons(x1, x2), s(x0), true) → IF2(cons(x1, x2), s(x0), false)

The TRS R consists of the following rules:

length(nil) → 0
length(cons(h, t)) → s(length(t))
leq(0, m) → true
leq(s(n), s(m)) → leq(n, m)
leq(s(n), 0) → false
sndsplit(0, x) → x
sndsplit(s(n), nil) → nil
sndsplit(s(n), cons(h, t)) → sndsplit(n, t)

The set Q consists of the following terms:

sndsplit(0, x0)
sndsplit(s(x0), nil)
sndsplit(s(x0), cons(x1, x2))
leq(0, x0)
leq(s(x0), 0)
leq(s(x0), s(x1))
length(nil)
length(cons(x0, x1))

We have to consider all minimal (P,Q,R)-chains.
The approximation of the Dependency Graph [15,17,22] contains 0 SCCs with 3 less nodes.
