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

APP'(app'(app, app'(app'(add, n), app'(app'(add, n''), app'(app'(add, n'''), app'(app'(add, n'0), app'(app'(add, n'1), x')))))), y''''') -> APP'(app'(add, n), app'(app'(add, n''), app'(app'(add, n'''), app'(app'(add, n'0), app'(app'(add, n'1), app'(app'(app, x'), y'''''))))))

two new Dependency Pairs are created:

APP'(app'(app, app'(app'(add, n), app'(app'(add, n''), app'(app'(add, n'''), app'(app'(add, n'0), app'(app'(add, n'1), nil)))))), y'''''') -> APP'(app'(add, n), app'(app'(add, n''), app'(app'(add, n'''), app'(app'(add, n'0), app'(app'(add, n'1), y'''''')))))
APP'(app'(app, app'(app'(add, n), app'(app'(add, n''), app'(app'(add, n'''), app'(app'(add, n'0), app'(app'(add, n'1), app'(app'(add, n'2), x''))))))), y'''''') -> APP'(app'(add, n), app'(app'(add, n''), app'(app'(add, n'''), app'(app'(add, n'0), app'(app'(add, n'1), app'(app'(add, n'2), app'(app'(app, x''), y'''''')))))))

The transformation is resulting in one new DP problem:

     ↳DPs

       →DP Problem 1

         ↳Nar

           →DP Problem 2
