↳Dependency Pair Analysis

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

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

Furthermore,

↳Narrowing Transformation

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

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

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

The transformation is resulting in one new DP problem:

↳Remaining Obligation(s)

The following remains to be proven:

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

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