Termination w.r.t. Q proof of TRS/AG01#3.53a.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:

g₂(x, y) -> x
g₂(x, y) -> y
f₃(s₁(x), y, y) -> f₃(y, x, s₁(x))

Q is empty.

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

g₂(x, y) -> x
g₂(x, y) -> y
f₃(s₁(x), y, y) -> f₃(y, x, s₁(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:

F₃(s₁(x), y, y) -> F₃(y, x, s₁(x))

The TRS R consists of the following rules:

g₂(x, y) -> x
g₂(x, y) -> y
f₃(s₁(x), y, y) -> f₃(y, x, s₁(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:

F₃(s₁(x), y, y) -> F₃(y, x, s₁(x))

The TRS R consists of the following rules:

g₂(x, y) -> x
g₂(x, y) -> y
f₃(s₁(x), y, y) -> f₃(y, x, s₁(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.

F₃(s₁(x), y, y) -> F₃(y, x, s₁(x))

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(F₃(x₁, x₂, x₃)) = x₁ + x₂
POL(s₁(x₁)) = 2 + 2·x₁

The following usable rules [14] were oriented: none

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