We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


AFTER2(s1(N), cons2(X, XS)) -> AFTER2(N, activate1(XS))
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( AFTER2(x1, x2) ) = x1


POL( s1(x1) ) = x1 + 1



The following usable rules [14] were oriented: none
