We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


AND2(xor2(x, y), z) -> AND2(y, z)
AND2(xor2(x, y), z) -> AND2(x, z)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( AND2(x1, x2) ) = x1 + x2 + 1


POL( xor2(x1, x2) ) = x1 + x2 + 1



The following usable rules [14] were oriented: none
