Termination w.r.t. Q proof of TRS/AG01#3.37.trs

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:

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

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.

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)

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 interpretation [21]:

POL(0) = 2
POL(EVENODD₂(x₁, x₂)) = 3·x₁
POL(s₁(x₁)) = 3 + x₁

The following usable rules [14] were oriented: none
