Strategy:

innermost

The following dependency pair can be strictly oriented:

LOG'(I(x)) -> LOG'(x)

There are no usable rules for innermost that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:

POL(LOG'(x₁)) = x₁

POL(I(x₁)) = 1 + x₁

resulting in one new DP problem.
