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)) -> g1(f1(f1(X)))
f1(h1(X)) -> h1(g1(X))

Q is empty.

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

f1(g1(X)) -> g1(f1(f1(X)))
f1(h1(X)) -> h1(g1(X))

Q is empty.

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

F1(g1(X)) -> F1(X)

The TRS R consists of the following rules:

f1(g1(X)) -> g1(f1(f1(X)))
f1(h1(X)) -> h1(g1(X))

The set Q consists of the following terms:

f1(g1(x0))

Q DP problem:
The TRS P consists of the following rules:

F1(g1(X)) -> F1(f1(X))
F1(g1(X)) -> F1(X)

The TRS R consists of the following rules:

f1(g1(X)) -> g1(f1(f1(X)))
f1(h1(X)) -> h1(g1(X))

The set Q consists of the following terms:

f1(g1(x0))
f1(h1(x0))

We have to consider all minimal (P,Q,R)-chains.
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(f1(X))
F1(g1(X)) -> F1(X)
Used argument filtering: F1(x1)  =  x1
g1(x1)  =  g1(x1)
f1(x1)  =  x1
h1(x1)  =  h
Used ordering: Quasi Precedence: trivial

Q DP problem:
P is empty.
The TRS R consists of the following rules:

f1(g1(X)) -> g1(f1(f1(X)))
f1(h1(X)) -> h1(g1(X))

The set Q consists of the following terms:

f1(g1(x0))
f1(h1(x0))

We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
