R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
F(f(x)) -> F(c(f(x)))
F(f(x)) -> F(d(f(x)))
G(c(h(0))) -> G(d(1))
G(c(1)) -> G(d(h(0)))
G(h(x)) -> G(x)
Furthermore, R contains one SCC.

↳Polynomial Ordering
Dependency Pair:
G(h(x)) -> G(x)
Rules:
f(f(x)) -> f(c(f(x)))
f(f(x)) -> f(d(f(x)))
g(c(x)) -> x
g(d(x)) -> x
g(c(h(0))) -> g(d(1))
g(c(1)) -> g(d(h(0)))
g(h(x)) -> g(x)
Strategy:
innermost
The following dependency pair can be strictly oriented:
G(h(x)) -> G(x)
There are no usable rules for innermost that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(G(x1)) | = x1 |
| POL(h(x1)) | = 1 + x1 |
resulting in one new DP problem.

Rules:
f(f(x)) -> f(c(f(x)))
f(f(x)) -> f(d(f(x)))
g(c(x)) -> x
g(d(x)) -> x
g(c(h(0))) -> g(d(1))
g(c(1)) -> g(d(h(0)))

Using the Dependency Graph resulted in no new DP problems.
