We consider the following Problem:
Strict Trs:
{ or(x, x) -> x
, and(x, x) -> x
, not(not(x)) -> x
, not(and(x, y)) -> or(not(x), not(y))
, not(or(x, y)) -> and(not(x), not(y))}
StartTerms: basic terms
Strategy: innermost
Certificate: YES(?,O(n^1))
Proof:
We consider the following Problem:
Strict Trs:
{ or(x, x) -> x
, and(x, x) -> x
, not(not(x)) -> x
, not(and(x, y)) -> or(not(x), not(y))
, not(or(x, y)) -> and(not(x), not(y))}
StartTerms: basic terms
Strategy: innermost
Certificate: YES(?,O(n^1))
Proof:
The weightgap principle applies, where following rules are oriented strictly:
TRS Component:
{ or(x, x) -> x
, not(or(x, y)) -> and(not(x), not(y))}
Interpretation of nonconstant growth:
-------------------------------------
The following argument positions are usable:
Uargs(or) = {1, 2}, Uargs(and) = {1, 2}, Uargs(not) = {}
We have the following EDA-non-satisfying and IDA(1)-non-satisfying matrix interpretation:
Interpretation Functions:
or(x1, x2) = [1 0] x1 + [1 1] x2 + [2]
[0 1] [0 0] [0]
and(x1, x2) = [1 0] x1 + [1 1] x2 + [0]
[0 1] [0 0] [0]
not(x1) = [1 0] x1 + [0]
[0 0] [1]
The strictly oriented rules are moved into the weak component.

The problem is match-bounded by 0.
The enriched problem is compatible with the following automaton:

, not_0(2) -> 1}
Hurray, we answered YES(?,O(n^1))
