R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(x, f(a, a)) -> F(f(f(a, a), a), f(a, x))
F(x, f(a, a)) -> F(f(a, a), a)
F(x, f(a, a)) -> F(a, x)
Furthermore, R contains one SCC.

↳Remaining Obligation(s)
The following remains to be proven:
Dependency Pairs:
F(x, f(a, a)) -> F(a, x)
F(x, f(a, a)) -> F(f(f(a, a), a), f(a, x))
Rule:
f(x, f(a, a)) -> f(f(f(a, a), a), f(a, x))
