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(quot) = {1},
uargs(s) = {1}
Following symbols are considered usable:

TcT has computed the following interpretation:
p(0) = [8]
p(minus) = [1] x1 + [0]
p(quot) = [1] x1 + [1] x2 + [0]
p(s) = [1] x1 + [8]
Following rules are strictly oriented:
minus(s(x),s(y)) = [1] x + [8]
> [1] x + [0]
= minus(x,y)
quot(0(),s(y)) = [1] y + [16]
> [8]
= 0()
Following rules are (at-least) weakly oriented:
minus(x,0()) = [1] x + [0]
>= [1] x + [0]
= x
quot(s(x),s(y)) = [1] x + [1] y + [16]
>= [1] x + [1] y + [16]
= s(quot(minus(x,y),s(y)))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
