The following pairs can be oriented strictly and are deleted.


G1(h1(x)) -> G1(x)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( G1(x1) ) = max{0, x1 - 2}


POL( h1(x1) ) = x1 + 3



The following usable rules [14] were oriented: none
