, implies(false(), y) -> not(false())
, implies(x, false()) -> not(x)

We consider the following Problem:

Proof:
The weightgap principle applies, where following rules are oriented strictly:
TRS Component:
{ and(x, false()) -> false()
, and(x, not(false())) -> x
, implies(false(), y) -> not(false())}
Interpretation of nonconstant growth:
-------------------------------------
The following argument positions are usable:
Uargs(and) = {}, Uargs(not) = {}, Uargs(implies) = {2}
We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
Interpretation Functions:
and(x1, x2) = [1 0] x1 + [0 0] x2 + [1]
[0 1] [0 0] [1]
false() = [0]
[0]
not(x1) = [1 0] x1 + [0]
[0 1] [0]
implies(x1, x2) = [1 0] x1 + [1 0] x2 + [1]
[0 0] [1 0] [1]
The strictly oriented rules are moved into the weak component.
