Termination w.r.t. Q proof of TRS/Zantemajw26.trs

Termination w.r.t. Q of the following Term Rewriting System could not be shown:

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

f₂(f₂(a, a), x) -> f₂(a, f₂(x, f₂(a, f₂(a, a))))

Q is empty.

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

f₂(f₂(a, a), x) -> f₂(a, f₂(x, f₂(a, f₂(a, a))))

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:

F₂(f₂(a, a), x) -> F₂(a, f₂(x, f₂(a, f₂(a, a))))
F₂(f₂(a, a), x) -> F₂(a, f₂(a, a))
F₂(f₂(a, a), x) -> F₂(x, f₂(a, f₂(a, a)))

The TRS R consists of the following rules:

f₂(f₂(a, a), x) -> f₂(a, f₂(x, f₂(a, f₂(a, a))))

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