R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(h(x)) -> F(i(x))
F(h(x)) -> I(x)
G(i(x)) -> G(h(x))
G(i(x)) -> H(x)
Furthermore, R contains two SCCs.

↳Polo
Dependency Pair:
F(h(x)) -> F(i(x))
Rules:
f(h(x)) -> f(i(x))
g(i(x)) -> g(h(x))
h(a) -> b
i(a) -> b
Strategy:
innermost
The following dependency pair can be strictly oriented:
F(h(x)) -> F(i(x))
Additionally, the following usable rule for innermost can be oriented:
i(a) -> b
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(i(x1)) | = 0 |
| POL(b) | = 0 |
| POL(h(x1)) | = 1 |
| POL(a) | = 0 |
| POL(F(x1)) | = x1 |
resulting in one new DP problem.
