Strategy:

innermost




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

+'(p10, +(p2, x)) -> +'(p10, x)
one new Dependency Pair is created:

+'(p10, +(p2, +(p2, x''))) -> +'(p10, +(p2, x''))

The transformation is resulting in no new DP problems.
