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

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

f1(c2(X, s1(Y))) -> f1(c2(s1(X), Y))
g1(c2(s1(X), Y)) -> f1(c2(X, s1(Y)))

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(c2(X, s1(Y))) -> F1(c2(s1(X), Y))
Used argument filtering: F1(x1)  =  x1
c2(x1, x2)  =  x2
s1(x1)  =  s1(x1)
Used ordering: Quasi Precedence: trivial
