On this DP problem, a Narrowing SCC transformation can be performed.
As a result of transforming the rule

-'(O(x), I(y)) -> -'(-(x, y), I(1))
six new Dependency Pairs are created:

-'(O(x''), I(0)) -> -'(x'', I(1))
-'(O(0), I(y')) -> -'(0, I(1))
-'(O(O(x'')), I(O(y''))) -> -'(O(-(x'', y'')), I(1))
-'(O(O(x'')), I(I(y''))) -> -'(I(-(-(x'', y''), I(1))), I(1))
-'(O(I(x'')), I(O(y''))) -> -'(I(-(x'', y'')), I(1))
-'(O(I(x'')), I(I(y''))) -> -'(O(-(x'', y'')), I(1))

The transformation is resulting in no new DP problems.

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.
