↳Narrowing Transformation

f(f(x, a), a) -> f(f(f(a, a), f(x, a)), a)

innermost

On this DP problem, a Narrowing SCC transformation can be performed.

As a result of transforming the rule

one new Dependency Pair is created:

F(f(x, a), a) -> F(f(f(a, a), f(x, a)), a)

F(f(f(x'', a), a), a) -> F(f(f(a, a), f(f(f(a, a), f(x'', a)), a)), a)

The transformation is resulting in no new DP problems.
