↳Dependency Pair Analysis

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

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

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

Furthermore,

↳Narrowing Transformation

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

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

The transformation is resulting in one new DP problem:

→DP Problem 1

↳Nar

→DP Problem 2

↳Remaining Obligation(s)

The following remains to be proven:

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

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