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):

TcT has computed the following interpretation:
p(f) = [0]
p(g) = [0]
p(s) = [0]
p(f#) = [6]
p(g#) = [2] x1 + [1] x2 + [0]
p(c_1) = [5]
p(c_2) = [2] x1 + [0]
p(c_3) = [1] x1 + [0]
Following rules are strictly oriented:
f#(s(x),y,y) = [6]
> [5]

Following rules are (at-least) weakly oriented:
g#(x,y) = [2] x + [1] y + [0]

g#(x,y) = [2] x + [1] y + [0]

WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following constant growth matrix-interpretation:

TcT has computed the following interpretation:
p(f) = [8] x2 + [0]
p(g) = [1] x1 + [1] x2 + [0]
p(s) = [0]
p(f#) = [4] x1 + [8] x3 + [0]
p(g#) = [9] x1 + [4]
p(c_1) = [2] x1 + [0]
p(c_2) = [2]
p(c_3) = [2]
Following rules are strictly oriented:
g#(x,y) = [9] x + [4]
> [2]
= c_2(x)
g#(x,y) = [9] x + [4]
> [2]

Following rules are (at-least) weakly oriented:
f#(s(x),y,y) = [8] y + [0]
>= [8] y + [0]
= c_1(f#(y,x,s(x)))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
