[x, y, z]

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

Termination of R to be shown.

`     ↳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`
`         ↳Argument Filtering and Ordering`
`       →DP Problem 2`
`         ↳Remaining`

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)

There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System:
F(x1) -> F(x1)
+(x1, x2) -> +(x1, x2)

`         ↳Remaining`

Dependency Pair:

Rules:

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

Using the Dependency Graph resulted in no new DP problems.

The following remains to be proven:
Dependency Pairs:

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

Rules:

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