   R
Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

Remaining Obligation(s)




The following remains to be proven:
Dependency Pairs:

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


Rule:


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