Termination w.r.t. Q proof of TRS/SK902.37.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:

and₃(not₁(not₁(x)), y, not₁(z)) -> and₃(y, band₂(x, z), x)

Q is empty.

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

and₃(not₁(not₁(x)), y, not₁(z)) -> and₃(y, band₂(x, z), x)

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:

AND₃(not₁(not₁(x)), y, not₁(z)) -> AND₃(y, band₂(x, z), x)

The TRS R consists of the following rules:

and₃(not₁(not₁(x)), y, not₁(z)) -> and₃(y, band₂(x, z), x)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.

Q DP problem:
The TRS P consists of the following rules:

AND₃(not₁(not₁(x)), y, not₁(z)) -> AND₃(y, band₂(x, z), x)

The TRS R consists of the following rules:

and₃(not₁(not₁(x)), y, not₁(z)) -> and₃(y, band₂(x, z), x)

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.

AND₃(not₁(not₁(x)), y, not₁(z)) -> AND₃(y, band₂(x, z), x)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( not₁(x₁) ) = x₁ + 3

POL( band₂(x₁, x₂) ) = max{0, -3}

POL( AND₃(x₁, ..., x₃) ) = 2x₁ + 2x₂

The following usable rules [14] were oriented: none

Q DP problem:
P is empty.
The TRS R consists of the following rules:

and₃(not₁(not₁(x)), y, not₁(z)) -> and₃(y, band₂(x, z), x)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
