NaturalMI {miDimension = 1, miDegree = 1, miKind = Algebraic, uargs = UArgs, urules = URules, selector = Just any strict-rules, greedy = NoGreedy}
Proof:
We apply a matrix interpretation of kind constructor based matrix interpretation:
The following argument positions are considered usable:
uargs(u21) = {1},
uargs(u22) = {1}
Following symbols are considered usable:
{ackin,u21}
TcT has computed the following interpretation:
p(ackin) = [0]
p(ackout) = [1]
p(s) = [2]
p(u21) = [8] x1 + [0]
p(u22) = [1] x1 + [2]
Following rules are strictly oriented:
u21(ackout(X),Y) = [8]
> [2]
= u22(ackin(Y,X))
Following rules are (at-least) weakly oriented:
ackin(s(X),s(Y)) = [0]
>= [0]
= u21(ackin(s(X),Y),X)

WeightGap {wgDimension = 1, wgDegree = 1, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following nonconstant growth matrix-interpretation:

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