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.

ACTIVE₁(sieve₁(X)) -> ACTIVE₁(X)

The remaining pairs can at least by weakly be oriented.
none
Used ordering: Combined order from the following AFS and order.
ACTIVE₁(x1) = ACTIVE₁(x1)
sieve₁(x1) = sieve₁(x1)

Lexicographic Path Order [19].
Precedence:

sieve₁ > ACTIVE₁
