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(f) = {1}
Following symbols are considered usable:
{}
TcT has computed the following interpretation:
p(f) = [1] x1 + [5]
p(g) = [4] x1 + [1] x2 + [0]
p(h) = [4] x1 + [1] x2 + [14]
Following rules are strictly oriented:
g(f(x),y) = [4] x + [1] y + [20]
> [4] x + [1] y + [19]
= f(h(x,y))
h(x,y) = [4] x + [1] y + [14]
> [4] x + [1] y + [5]
= g(x,f(y))
Following rules are (at-least) weakly oriented:
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
