f#(a(g(X))) -> c_2(b#(X))
f#(f(X)) -> c_3(f#(a(b(f(X)))))

WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following constant growth matrix-interpretation:
We apply a matrix interpretation of kind constructor based matrix interpretation (containing no more than 0 non-zero interpretation-entries in the diagonal of the component-wise maxima):
The following argument positions are considered usable:
uargs(c_2) = {1}
Following symbols are considered usable:
{}
TcT has computed the following interpretation:
p(a) = [0]
p(b) = [0]
p(f) = [0]
p(g) = [0]
p(b#) = [0]
p(f#) = [1]
p(c_1) = [0]
p(c_2) = [1] x1 + [0]
p(c_3) = [0]
Following rules are strictly oriented:
f#(a(g(X))) = [1]
> [0]
= c_2(b#(X))
Following rules are (at-least) weakly oriented:
b#(X) = [0]
>= [0]
= c_1(X)
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
