`     ↳Dependency Pair Analysis`

R contains the following Dependency Pairs:

F(+(x, 0)) -> F(x)
+'(x, +(y, z)) -> +'(+(x, y), z)
+'(x, +(y, z)) -> +'(x, y)

Furthermore, R contains two SCCs.

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

Dependency Pair:

F(+(x, 0)) -> F(x)

Rules:

f(+(x, 0)) -> f(x)
+(x, +(y, z)) -> +(+(x, y), z)

The following dependency pair can be strictly oriented:

F(+(x, 0)) -> F(x)

Additionally, the following rules can be oriented:

f(+(x, 0)) -> f(x)
+(x, +(y, z)) -> +(+(x, y), z)

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

resulting in one new DP problem.

Dependency Pair:

Rules:

f(+(x, 0)) -> f(x)
+(x, +(y, z)) -> +(+(x, y), z)

Using the Dependency Graph resulted in no new DP problems.
