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

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

The following dependency pair can be strictly oriented:

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

Additionally, the following usable rule w.r.t. to the implicit AFS can be oriented:

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

Used ordering: Polynomial ordering with Polynomial interpretation:

_{ }^{ }POL(a)= 1 _{ }^{ }_{ }^{ }POL(f(x)_{1}, x_{2})= 0 _{ }^{ }_{ }^{ }POL(F(x)_{1}, x_{2})= x _{2}_{ }^{ }

resulting in one new DP problem.
