f(0) -> 1
f(s(x)) -> g(f(x))
f(s(x)) -> +(f(x), s(f(x)))
g(x) -> +(x, s(x))

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

→DP Problem 1
↳Polynomial Ordering
Dependency Pair:
F(s(x)) -> F(x)
Rules:
f(0) -> 1
f(s(x)) -> g(f(x))
f(s(x)) -> +(f(x), s(f(x)))
g(x) -> +(x, s(x))
The following dependency pair can be strictly oriented:
F(s(x)) -> F(x)
Additionally, the following rules can be oriented:
f(0) -> 1
f(s(x)) -> g(f(x))
f(s(x)) -> +(f(x), s(f(x)))
g(x) -> +(x, s(x))
Used ordering: Polynomial ordering with Polynomial interpretation:
| POL(0) | = 0 |
| POL(g(x1)) | = 0 |
| POL(1) | = 0 |
| POL(s(x1)) | = 1 + x1 |
| POL(f(x1)) | = 0 |
| POL(+(x1, x2)) | = 0 |
| POL(F(x1)) | = x1 |
resulting in one new DP problem.

↳Dependency Graph
Dependency Pair:
Rules:
f(0) -> 1
f(s(x)) -> g(f(x))
f(s(x)) -> +(f(x), s(f(x)))
g(x) -> +(x, s(x))
Using the Dependency Graph resulted in no new DP problems.
