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 Order [17,21] with Interpretation:

POL( C1(x1) ) = max{0, x1 - 2}


POL( b1(x1) ) = x1 + 1


POL( a1(x1) ) = x1 + 2



The following usable rules [14] were oriented: none
