WeightGap {wgDimension = 1, wgDegree = 0, 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(u21) = {1},
uargs(u22) = {1},
uargs(u21#) = {1},
uargs(c_1) = {1},
uargs(c_2) = {1}

TcT has computed the following interpretation:
p(ackin) = [0]
p(ackout) = [3]
p(s) = [1] x1 + [0]
p(u21) = [1] x1 + [0]
p(u22) = [1] x1 + [0]
p(ackin#) = [8] x1 + [0]
p(u21#) = [1] x1 + [8] x2 + [0]
p(c_1) = [1] x1 + [0]
p(c_2) = [1] x1 + [0]
Following rules are strictly oriented:
u21#(ackout(X),Y) = [8] Y + [3]
> [8] Y + [0]
= c_2(ackin#(Y,X))
u21(ackout(X),Y) = [3]
> [0]
= u22(ackin(Y,X))
Following rules are (at-least) weakly oriented:
ackin#(s(X),s(Y)) = [8] X + [0]
>= [8] X + [0]
= c_1(u21#(ackin(s(X),Y),X))
ackin(s(X),s(Y)) = [0]
>= [0]
= u21(ackin(s(X),Y),X)
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
