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(x)) → g(g(f(x)))
f(g(x)) → g(g(g(x)))
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
f(g(x)) → g(g(f(x)))
f(g(x)) → g(g(g(x)))
Q is empty.
Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
F(g(x)) → F(x)
The TRS R consists of the following rules:
f(g(x)) → g(g(f(x)))
f(g(x)) → g(g(g(x)))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.

Q DP problem:
The TRS P consists of the following rules:
F(g(x)) → F(x)
The TRS R consists of the following rules:
f(g(x)) → g(g(f(x)))
f(g(x)) → g(g(g(x)))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].
The following pairs can be oriented strictly and are deleted.
F(g(x)) → F(x)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
F(x1) = F(x1)
g(x1) = g(x1)
Lexicographic Path Order [19].
Precedence:
g1 > F1

Q DP problem:
P is empty.
The TRS R consists of the following rules:
f(g(x)) → g(g(f(x)))
f(g(x)) → g(g(g(x)))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
