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(X)) → f(a(b(f(X))))
f(a(g(X))) → b(X)
b(X) → a(X)
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
f(f(X)) → f(a(b(f(X))))
f(a(g(X))) → b(X)
b(X) → a(X)
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(f(X)) → F(a(b(f(X))))
F(a(g(X))) → B(X)
F(f(X)) → B(f(X))
The TRS R consists of the following rules:
f(f(X)) → f(a(b(f(X))))
f(a(g(X))) → b(X)
b(X) → a(X)
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
