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(cons) = {2},
uargs(n__add) = {1},
uargs(n__fst) = {1,2},
uargs(n__len) = {1},
uargs(s) = {1}
Following symbols are considered usable:
{}
TcT has computed the following interpretation:
p(0) = [0]
p(activate) = [4] x1 + [0]
p(add) = [4] x1 + [4] x2 + [0]
p(cons) = [1] x2 + [0]
p(from) = [0]
p(fst) = [4] x1 + [4] x2 + [5]
p(len) = [4] x1 + [4]
p(n__add) = [1] x1 + [1] x2 + [0]
p(n__from) = [0]
p(n__fst) = [1] x1 + [1] x2 + [2]
p(n__len) = [1] x1 + [1]
p(nil) = [2]
p(s) = [1] x1 + [2]
Following rules are strictly oriented:
len(cons(X,Z)) = [4] Z + [4]
> [4] Z + [3]
= s(n__len(activate(Z)))
Following rules are (at-least) weakly oriented:
activate(X) = [4] X + [0]
>= [1] X + [0]
= X
activate(n__add(X1,X2)) = [4] X1 + [4] X2 + [0]
>= [4] X1 + [4] X2 + [0]
= add(X1,X2)
activate(n__from(X)) = [0]
>= [0]
= from(X)
activate(n__fst(X1,X2)) = [4] X1 + [4] X2 + [8]
>= [4] X1 + [4] X2 + [5]
= fst(X1,X2)
activate(n__len(X)) = [4] X + [4]
>= [4] X + [4]
= len(X)
add(X1,X2) = [4] X1 + [4] X2 + [0]
>= [1] X1 + [1] X2 + [0]
= n__add(X1,X2)
add(0(),X) = [4] X + [0]
>= [1] X + [0]
= X
add(s(X),Y) = [4] X + [4] Y + [8]
>= [4] X + [1] Y + [2]
= s(n__add(activate(X),Y))
from(X) = [0]
>= [0]
= cons(X,n__from(s(X)))
from(X) = [0]
>= [0]
= n__from(X)
fst(X1,X2) = [4] X1 + [4] X2 + [5]
>= [1] X1 + [1] X2 + [2]
= n__fst(X1,X2)
fst(0(),Z) = [4] Z + [5]
>= [2]
= nil()
fst(s(X),cons(Y,Z)) = [4] X + [4] Z + [13]
>= [4] X + [4] Z + [2]
= cons(Y
,n__fst(activate(X)
,activate(Z)))
len(X) = [4] X + [4]
>= [1] X + [1]
= n__len(X)
len(nil()) = [12]
>= [0]
= 0()
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
