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(+) = {2},
uargs(s) = {1}
Following symbols are considered usable:
{}
TcT has computed the following interpretation:
p(+) = [1] x1 + [1] x2 + [0]
p(0) = [1]
p(s) = [1] x1 + [0]
Following rules are strictly oriented:
+(0(),y) = [1] y + [1]
> [1] y + [0]
= y
+(s(x),0()) = [1] x + [1]
> [1] x + [0]
= s(x)
Following rules are (at-least) weakly oriented:
+(s(x),s(y)) = [1] x + [1] y + [0]
>= [1] x + [1] y + [1]
= s(+(s(x),+(y,0())))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
