WeightGap {wgDimension = 1, wgDegree = 1, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following nonconstant growth matrix-interpretation:
We apply a matrix interpretation of kind constructor based matrix interpretation:
The following argument positions are considered usable:
uargs(+) = {1},

TcT has computed the following interpretation:
p(+) = [1] x1 + [10]
p(0) = [0]
p(1) = [2]
p(f) = [8] x1 + [0]
p(g) = [7] x1 + [1] x2 + [0]
p(s) = [1] x1 + [3]
Following rules are strictly oriented:
+(x,0()) = [1] x + [10]

f(s(x)) = [8] x + [24]

g(s(x),y) = [7] x + [1] y + [21]
> [7] x + [1] y + [13]
= g(x,s(+(y,x)))
Following rules are (at-least) weakly oriented:
+(x,s(y)) = [1] x + [10]

f(0()) = [0]
>= [2]

g(0(),y) = [1] y + [0]
>= [1] y + [0]
= y
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
