Termination w.r.t. Q proof of /home/nowonder/forschung/aprove/satrung/aprove/lpar4/SK90SLASH2.28.trs

Termination w.r.t. Q of the following Term Rewriting System could be proven:

Q restricted rewrite system:
The TRS R consists of the following rules:

dfib₂(s₁(s₁(x)), y) -> dfib₂(s₁(x), dfib₂(x, y))

Q is empty.

  ↳ Non-Overlap Check

Q restricted rewrite system:
The TRS R consists of the following rules:

dfib₂(s₁(s₁(x)), y) -> dfib₂(s₁(x), dfib₂(x, y))

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.

Q restricted rewrite system:
The TRS R consists of the following rules:

dfib₂(s₁(s₁(x)), y) -> dfib₂(s₁(x), dfib₂(x, y))

The set Q consists of the following terms:

dfib₂(s₁(s₁(x0)), x1)

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

DFIB₂(s₁(s₁(x)), y) -> DFIB₂(x, y)
DFIB₂(s₁(s₁(x)), y) -> DFIB₂(s₁(x), dfib₂(x, y))

The TRS R consists of the following rules:

dfib₂(s₁(s₁(x)), y) -> dfib₂(s₁(x), dfib₂(x, y))

The set Q consists of the following terms:

dfib₂(s₁(s₁(x0)), x1)

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

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

DFIB₂(s₁(s₁(x)), y) -> DFIB₂(x, y)
DFIB₂(s₁(s₁(x)), y) -> DFIB₂(s₁(x), dfib₂(x, y))

The TRS R consists of the following rules:

dfib₂(s₁(s₁(x)), y) -> dfib₂(s₁(x), dfib₂(x, y))

The set Q consists of the following terms:

dfib₂(s₁(s₁(x0)), x1)

We have to consider all minimal (P,Q,R)-chains.
By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

DFIB₂(s₁(s₁(x)), y) -> DFIB₂(x, y)
DFIB₂(s₁(s₁(x)), y) -> DFIB₂(s₁(x), dfib₂(x, y))

Used argument filtering: DFIB₂(x1, x2) = x1
s₁(x1) = s₁(x1)
Used ordering: Quasi Precedence: trivial

Q DP problem:
P is empty.
The TRS R consists of the following rules:

dfib₂(s₁(s₁(x)), y) -> dfib₂(s₁(x), dfib₂(x, y))

The set Q consists of the following terms:

dfib₂(s₁(s₁(x0)), x1)

We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
