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 oriented strictly and are deleted.

FSTSPLIT₂(s₁(n), cons₂(h, t)) -> FSTSPLIT₂(n, t)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(FSTSPLIT₂(x₁, x₂)) = 3·x₁ + 3·x₂
POL(cons₂(x₁, x₂)) = 2·x₂
POL(s₁(x₁)) = 2 + 2·x₁

The following usable rules [14] were oriented: none
