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(+) = {1,2}
Following symbols are considered usable:
{sqr,sum}
TcT has computed the following interpretation:
p(*) = [0]
p(+) = [1] x1 + [1] x2 + [4]
p(0) = [0]
p(s) = [1] x1 + [1]
p(sqr) = [1]
p(sum) = [8] x1 + [0]
Following rules are strictly oriented:
sqr(x) = [1]
> [0]
= *(x,x)
sum(s(x)) = [8] x + [8]
> [8] x + [4]
= +(*(s(x),s(x)),sum(x))
sum(s(x)) = [8] x + [8]
> [8] x + [5]
= +(sqr(s(x)),sum(x))
Following rules are (at-least) weakly oriented:
sum(0()) = [0]
>= [0]
= 0()

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:

TcT has computed the following interpretation:
p(*) = [0]
p(+) = [1] x1 + [1] x2 + [0]
p(0) = [0]
p(s) = [0]
p(sqr) = [0]
p(sum) = [5]
Following rules are strictly oriented:
sum(0()) = [5]
> [0]
= 0()
Following rules are (at-least) weakly oriented:
sqr(x) = [0]
>= [0]
= *(x,x)
sum(s(x)) = [5]
>= [5]
= +(*(s(x),s(x)),sum(x))
sum(s(x)) = [5]
>= [5]
= +(sqr(s(x)),sum(x))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
