Term Rewriting System R:
[x]
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.

`   R`
`     ↳DPs`
`       →DP Problem 1`
`         ↳Argument Filtering and 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)

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: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
f > g > +
f > g > s
0 > 1

resulting in one new DP problem.
Used Argument Filtering System:
F(x1) -> F(x1)
s(x1) -> s(x1)
f(x1) -> f(x1)
g(x1) -> g(x1)
+(x1, x2) -> +(x1, x2)

`             ↳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.
