↳Forward Instantiation Transformation

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

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

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

As a result of transforming the rule

one new Dependency Pair is created:

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

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

The transformation is resulting in one new DP problem:

↳Narrowing Transformation

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

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

The transformation is resulting in no new DP problems.
