We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


C1(b1(a1(X))) -> C1(X)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(C1(x1)) = x1   
POL(a1(x1)) = x1   
POL(b1(x1)) = 1 + x1   

The following usable rules [14] were oriented: none
