Dependency Pair Analysis



R contains the following Dependency Pairs:

A(f, a(f, x)) -> A(x, x)
A(h, x) -> A(f, a(g, a(f, x)))
A(h, x) -> A(g, a(f, x))
A(h, x) -> A(f, x)

Furthermore, R contains one SCC.

Remaining Obligation(s)




The following remains to be proven:
Dependency Pairs:

A(h, x) -> A(f, x)
A(h, x) -> A(f, a(g, a(f, x)))
A(f, a(f, x)) -> A(x, x)


Rules:


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