Termination w.r.t. Q of the following Term Rewriting System could be proven:

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

not(true) → false
not(false) → true
evenodd(x, 0) → not(evenodd(x, s(0)))
evenodd(0, s(0)) → false
evenodd(s(x), s(0)) → evenodd(x, 0)

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

not(true) → false
not(false) → true
evenodd(x, 0) → not(evenodd(x, s(0)))
evenodd(0, s(0)) → false

Q is empty.

The TRS is overlay and locally confluent. By [15] we can switch to innermost.

Using Dependency Pairs [1,13] we result in the following initial DP problem:

We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

EVENODD(s(x), s(0)) → EVENODD(x, 0)

The remaining pairs can at least be oriented weakly.

EVENODD(x, 0) → EVENODD(x, s(0))

Used ordering: Combined order from the following AFS and order.
EVENODD(x1, x2) = EVENODD(x1)
0 = 0
s(x1) = s(x1)

Recursive path order with status [2].
Quasi-Precedence:

EVENODD₁ > [0, s_1]

Status:

EVENODD₁: multiset
0: multiset
s₁: multiset

The following usable rules [14] were oriented: none
