   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC. 


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




The following remains to be proven:
Dependency Pairs:

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


Rule:


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