We consider the following Problem:

We consider the following Problem:
Strict Trs:

Proof:
The weightgap principle applies, where following rules are oriented strictly:
TRS Component: {p(0()) -> g(0())}
Interpretation of nonconstant growth:
-------------------------------------
The following argument positions are usable:
Uargs(f) = {2}, Uargs(g) = {1}, Uargs(p) = {}, Uargs(s) = {1}
We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
Interpretation Functions:
f(x1, x2) = [0 2] x1 + [1 0] x2 + [1]
[0 0] [0 0] [1]
g(x1) = [1 0] x1 + [0]

s(x1) = [1 0] x1 + [0]
[0 0] [0]

The strictly oriented rules are moved into the weak component.
