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.

ACTIVE₁(filter₃(X1, X2, X3)) -> ACTIVE₁(X3)
ACTIVE₁(filter₃(X1, X2, X3)) -> ACTIVE₁(X1)
ACTIVE₁(filter₃(X1, X2, X3)) -> ACTIVE₁(X2)

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

POL(ACTIVE₁(x₁)) = 1 + x₁²
POL(filter₃(x₁, x₂, x₃)) = 1 + x₁ + x₂ + x₃

The following usable rules [14] were oriented: none
