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:

f1(g1(x)) -> f1(a2(g1(g1(f1(x))), g1(f1(x))))

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

f1(g1(x)) -> f1(a2(g1(g1(f1(x))), g1(f1(x))))

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.

By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

F1(g1(x)) -> F1(x)
Used argument filtering: F1(x1)  =  x1
g1(x1)  =  g1(x1)
Used ordering: Quasi Precedence: trivial
