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.
Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
F(g(h(x, y)), f(a, a)) → F(h(x, x), g(f(y, a)))
F(g(h(x, y)), f(a, a)) → F(y, a)
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 have to consider all minimal (P,Q,R)-chains.
