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:
f(f(a, f(x, a)), a) → f(a, f(f(x, a), a))
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
f(f(a, f(x, a)), a) → f(a, f(f(x, a), a))
Q is empty.
We use [23] with the following order to prove termination.
