The following pairs can be oriented strictly and are deleted.


F(x, y, s(z)) → F(0, 1, z)
The remaining pairs can at least be oriented weakly.

F(0, 1, x) → F(s(x), x, x)
Used ordering: Combined order from the following AFS and order.
F(x1, x2, x3)  =  F(x3)
s(x1)  =  s(x1)
0  =  0
1  =  1

Lexicographic Path Order [19].

s1 > F1 > 0
1 > F1 > 0

The following usable rules [14] were oriented: none
