WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following constant growth matrix-interpretation:
We apply a matrix interpretation of kind constructor based matrix interpretation (containing no more than 0 non-zero interpretation-entries in the diagonal of the component-wise maxima):
The following argument positions are considered usable:
none
Following symbols are considered usable:
{}
TcT has computed the following interpretation:
p(f) = [0]
p(g) = [10]
p(f#) = [1] x2 + [2] x3 + [3]
p(c_1) = [0]
p(c_2) = [3] x1 + [1]
p(c_3) = [1]
p(c_4) = [1]
p(c_5) = [2] x1 + [2]
Following rules are strictly oriented:
f#(x,x,y) = [1] x + [2] y + [3]
> [0]
= c_1(x)
f#(x,y,y) = [3] y + [3]
> [3] y + [1]
= c_2(y)
f#(x,y,g(y)) = [1] y + [23]
> [1]
= c_3(x)
f#(g(x),x,y) = [1] x + [2] y + [3]
> [2] y + [2]
= c_5(y)
Following rules are (at-least) weakly oriented:
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
