Q DP problem:
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(s₁(x), s₁(y), 0) -> f₃(x, y, s₁(0))
f₃(s₁(x), 0, s₁(z)) -> f₃(x, s₁(0), z)
f₃(0, s₁(0), s₁(0)) -> s₁(s₁(0))
f₃(s₁(x), s₁(y), s₁(z)) -> f₃(x, y, f₃(s₁(x), s₁(y), z))
f₃(0, s₁(s₁(y)), s₁(0)) -> f₃(0, y, s₁(0))
f₃(0, s₁(0), s₁(s₁(z))) -> f₃(0, s₁(0), z)
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.
