`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

F(c(s(x), y)) -> F(c(x, s(y)))
G(c(x, s(y))) -> G(c(s(x), y))

Furthermore, R contains two SCCs.

`       →DP Problem 1`
`         ↳Polynomial Ordering`
`       →DP Problem 2`
`         ↳Polo`

Dependency Pair:

F(c(s(x), y)) -> F(c(x, s(y)))

Rules:

f(c(s(x), y)) -> f(c(x, s(y)))
g(c(x, s(y))) -> g(c(s(x), y))

The following dependency pair can be strictly oriented:

F(c(s(x), y)) -> F(c(x, s(y)))

Additionally, the following rules can be oriented:

f(c(s(x), y)) -> f(c(x, s(y)))
g(c(x, s(y))) -> g(c(s(x), y))

Used ordering: Polynomial ordering with Polynomial interpretation:
 POL(c(x1, x2)) =  x1 POL(g(x1)) =  0 POL(s(x1)) =  1 + x1 POL(f(x1)) =  1 POL(F(x1)) =  x1

resulting in one new DP problem.

Dependency Pair:

Rules:

f(c(s(x), y)) -> f(c(x, s(y)))
g(c(x, s(y))) -> g(c(s(x), y))

Using the Dependency Graph resulted in no new DP problems.
