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

Termination of R to be shown.



   R
Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

Remaining Obligation(s)




The following remains to be proven:
Dependency Pairs:

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


Rule:


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