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 strictly oriented and are deleted.

F₃(s₁(x), s₁(y), s₁(z)) -> F₃(s₁(x), s₁(y), z)

The remaining pairs can at least by weakly be oriented.
none
Used ordering: Combined order from the following AFS and order.
F₃(x1, x2, x3) = F₁(x3)
s₁(x1) = s₁(x1)

Lexicographic Path Order [19].
Precedence:

s₁ > F₁

The following usable rules [14] were oriented: none

P is empty.
The TRS R consists of the following rules:

f₃(x, 0, 0) -> s₁(x)
f₃(0, y, 0) -> s₁(y)
f₃(0, 0, z) -> s₁(z)
f₃(s₁(0), y, z) -> f₃(0, s₁(y), s₁(z))

f₃(0, s₁(0), s₁(0)) -> s₁(s₁(0))

f₃(0, s₁(s₁(y)), s₁(s₁(z))) -> f₃(0, y, f₃(0, s₁(s₁(y)), s₁(z)))

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