   R
Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

Remaining Obligation(s)




The following remains to be proven:
Dependency Pairs:

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


Rule:


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