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:

f₁(0) -> cons₂(0, f₁(s₁(0)))
f₁(s₁(0)) -> f₁(p₁(s₁(0)))
p₁(s₁(0)) -> 0

Q is empty.

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

f₁(0) -> cons₂(0, f₁(s₁(0)))
f₁(s₁(0)) -> f₁(p₁(s₁(0)))
p₁(s₁(0)) -> 0

Q is empty.

The TRS is non-overlapping. Hence, we can switch to innermost.
