Termination w.r.t. Q proof of /home/nowonder/forschung/aprove/satrung/aprove/lpar16/SK90SLASH4.33.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:

a₁(b₁(a₁(x))) -> b₁(a₁(b₁(x)))

Q is empty.

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

a₁(b₁(a₁(x))) -> b₁(a₁(b₁(x)))

Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

A₁(b₁(a₁(x))) -> A₁(b₁(x))

The TRS R consists of the following rules:

a₁(b₁(a₁(x))) -> b₁(a₁(b₁(x)))

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

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

A₁(b₁(a₁(x))) -> A₁(b₁(x))

The TRS R consists of the following rules:

a₁(b₁(a₁(x))) -> b₁(a₁(b₁(x)))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be strictly oriented and are deleted.

A₁(b₁(a₁(x))) -> A₁(b₁(x))

The remaining pairs can at least by weakly be oriented.
none
Used ordering: Combined order from the following AFS and order.
A₁(x1) = A₁(x1)
b₁(x1) = x1
a₁(x1) = a₁(x1)

Lexicographic Path Order [19].
Precedence:

trivial

The following usable rules [14] were oriented: none

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

a₁(b₁(a₁(x))) -> b₁(a₁(b₁(x)))

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