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.

LOG'(O(x)) → LOG'(x)

The remaining pairs can at least be oriented weakly.

LOG'(I(x)) → LOG'(x)

Used ordering: Combined order from the following AFS and order.
LOG'(x1) = LOG'(x1)
O(x1) = O(x1)
I(x1) = x1

Lexicographic Path Order [19].
Precedence:
