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(plus) = {2}
Following symbols are considered usable:
{}
TcT has computed the following interpretation:
p(plus) = [1] x2 + [0]
p(s) = [1] x1 + [1]
p(times) = [1] x1 + [1] x2 + [8]
Following rules are strictly oriented:
times(X,s(Y)) = [1] X + [1] Y + [9]
> [1] X + [1] Y + [8]
= plus(X,times(Y,X))
Following rules are (at-least) weakly oriented:
plus(plus(X,Y),Z) = [1] Z + [0]
>= [1] Z + [0]
= plus(X,plus(Y,Z))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
