R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(g(X)) -> F(f(X))
F(g(X)) -> F(X)
Furthermore, R contains one SCC.

→DP Problem 1
↳Polynomial Ordering
Dependency Pairs:
F(g(X)) -> F(X)
F(g(X)) -> F(f(X))
Rules:
f(g(X)) -> g(f(f(X)))
f(h(X)) -> h(g(X))
The following dependency pairs can be strictly oriented:
F(g(X)) -> F(X)
F(g(X)) -> F(f(X))
Additionally, the following rules can be oriented:
f(g(X)) -> g(f(f(X)))
f(h(X)) -> h(g(X))
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(g(x1)) | = 1 + x1 |
| POL(h(x1)) | = 0 |
| POL(f(x1)) | = x1 |
| POL(F(x1)) | = 1 + x1 |
resulting in one new DP problem.

Dependency Pair:
Rules:
f(g(X)) -> g(f(f(X)))
f(h(X)) -> h(g(X))
Using the Dependency Graph resulted in no new DP problems.
