Q DP problem:
The TRS P consists of the following rules:
F1(g1(f1(X))) -> F1(g1(X))
The TRS R consists of the following rules:
f1(f1(X)) -> f1(g1(f1(g1(f1(X)))))
f1(g1(f1(X))) -> f1(g1(X))
Q is empty.
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(f1(X))) -> F1(g1(X))
Used argument filtering: F1(x1) = x1
g1(x1) = x1
f1(x1) = f1(x1)
Used ordering: Quasi Precedence:

Q DP problem:
P is empty.
The TRS R consists of the following rules:
f1(f1(X)) -> f1(g1(f1(g1(f1(X)))))
f1(g1(f1(X))) -> f1(g1(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.
