   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Remaining Obligation(s)




The following remains to be proven:
Dependency Pairs:

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


Rule:


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