We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


F(s(0)) → F(p(s(0)))
The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
F(x1)  =  x1
s(x1)  =  s(x1)
0  =  0
p(x1)  =  p

Recursive path order with status [2].
Quasi-Precedence:
[s1, p] > 0

Status:
s1: [1]
0: multiset
p: []


The following usable rules [14] were oriented:

p(s(0)) → 0
