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

f₂(s₁(x), y) -> f₂(x, s₁(x))
f₂(x, s₁(y)) -> f₂(y, x)

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

f₂(s₁(x), y) -> f₂(x, s₁(x))
f₂(x, s₁(y)) -> f₂(y, x)

Q is empty.

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

F₂(s₁(x), y) -> F₂(x, s₁(x))
F₂(x, s₁(y)) -> F₂(y, x)

The TRS R consists of the following rules:

f₂(s₁(x), y) -> f₂(x, s₁(x))
f₂(x, s₁(y)) -> f₂(y, x)

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