↳Overlay and local confluence Check

The TRS is overlay and locally confluent (all critical pairs are trivially joinable).Hence, we can switch to innermost.

As we are in the innermost case, we can delete all 1 non-usable-rules.

↳Instantiation Transformation

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

none

innermost

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

As a result of transforming the rule

one new Dependency Pair is created:

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

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

The transformation is resulting in no new DP problems.
