`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

`         ↳Polynomial Ordering`

Dependency Pair:

F(g(x)) -> F(x)

Rule:

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

Strategy:

innermost

The following dependency pair can be strictly oriented:

F(g(x)) -> F(x)

There are no usable rules for innermost that need to be oriented.

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(g(x1)) =  1 + x1 POL(F(x1)) =  x1

resulting in one new DP problem.

Dependency Pair:

Rule:

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

Strategy:

innermost

Using the Dependency Graph resulted in no new DP problems.
