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(g(h(x, y)), f(a, a)) → f(h(x, x), g(f(y, a)))

Q is empty.

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

f(g(h(x, y)), f(a, a)) → f(h(x, x), g(f(y, a)))

Q is empty.

We use [23] with the following order to prove termination.
