Q restricted rewrite system:
The TRS R consists of the following rules:

not1(true) -> false
not1(false) -> true
evenodd2(x, 0) -> not1(evenodd2(x, s1(0)))
evenodd2(0, s1(0)) -> false

Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

EVENODD2(x, 0) -> EVENODD2(x, s1(0))
EVENODD2(s1(x), s1(0)) -> EVENODD2(x, 0)
EVENODD2(x, 0) -> NOT1(evenodd2(x, s1(0)))

The TRS R consists of the following rules:

not1(true) -> false
not1(false) -> true
evenodd2(x, 0) -> not1(evenodd2(x, s1(0)))
evenodd2(0, s1(0)) -> false
evenodd2(s1(x), s1(0)) -> evenodd2(x, 0)

Q is empty.

We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


EVENODD2(s1(x), s1(0)) -> EVENODD2(x, 0)
The remaining pairs can at least be oriented weakly.

EVENODD2(x, 0) -> EVENODD2(x, s1(0))
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( EVENODD2(x1, x2) ) = x1


POL( s1(x1) ) = x1 + 1



The following usable rules [14] were oriented: none
