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

fac1(s1(x)) -> *2(fac1(p1(s1(x))), s1(x))
p1(s1(0)) -> 0
p1(s1(s1(x))) -> s1(p1(s1(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.

P1(s1(s1(x))) -> P1(s1(x))
Used argument filtering: P1(x1)  =  x1
s1(x1)  =  s1(x1)
Used ordering: Quasi Precedence: trivial
