We consider the following Problem:
Strict Trs:
{ g(f(x, y), z) -> f(x, g(y, z))
, g(h(x, y), z) -> g(x, f(y, z))
, g(x, h(y, z)) -> h(g(x, y), z)}

We consider the following Problem:

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

Hurray, we answered YES(?,O(n^1))
