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

f₂(x, 0) -> s₁(0)
f₂(s₁(x), s₁(y)) -> s₁(f₂(x, y))

By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

F₂(s₁(x), s₁(y)) -> F₂(x, y)

Used argument filtering: F₂(x1, x2) = x2
s₁(x1) = s₁(x1)
Used ordering: Precedence:
