↳Narrowing Transformation

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

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

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

As a result of transforming the rule

no new Dependency Pairs are created.

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

The transformation is resulting in one new DP problem:

↳Remaining Obligation(s)

The following remains to be proven:

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

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