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(x))

Q is empty.


QTRS
  ↳ DependencyPairsProof

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

a1(b1(a1(x))) -> b1(a1(x))

Q is empty.

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

a1(b1(a1(x))) -> b1(a1(x))

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

QDP
      ↳ PisEmptyProof

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

a1(b1(a1(x))) -> b1(a1(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.
