The following dependency pairs can be strictly oriented:

+'(I(x), I(y)) -> +'(x, y)
+'(O(x), I(y)) -> +'(x, y)


Additionally, the following usable rules for innermost can be oriented:

+(0, x) -> x
+(x, 0) -> x
+(O(x), O(y)) -> O(+(x, y))
+(O(x), I(y)) -> I(+(x, y))

Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(I(x1))=  1 + x1  
  POL(0)=  0  
  POL(O(x1))=  x1  
  POL(+(x1, x2))=  x1 + x2

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))
five new Dependency Pairs are created:

-'(O(x''), I(0)) -> -'(x'', 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.

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