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 interpretation [21]:

POL(AND2(x1, x2)) = 3·x1   
POL(xor2(x1, x2)) = 1 + 2·x1 + x2   

The following usable rules [14] were oriented: none
