R
↳Dependency Pair Analysis
R contains the following Dependency Pairs:
MERGE(++(x, y), ++(u, v)) -> MERGE(y, ++(u, v))
MERGE(++(x, y), ++(u, v)) -> MERGE(++(x, y), v)
Furthermore, R contains one SCC.

↳Argument Filtering and Ordering
Dependency Pair:
MERGE(++(x, y), ++(u, v)) -> MERGE(y, ++(u, v))
Rules:
merge(x, nil) -> x
merge(nil, y) -> y
merge(++(x, y), ++(u, v)) -> ++(x, merge(y, ++(u, v)))
merge(++(x, y), ++(u, v)) -> ++(u, merge(++(x, y), v))
The following dependency pair can be strictly oriented:
MERGE(++(x, y), ++(u, v)) -> MERGE(y, ++(u, v))
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: MERGE(x1, x2) -> MERGE(x1, x2)
++(x1, x2) -> ++(x1, x2)

↳Dependency Graph
Dependency Pair:
Rules:
merge(x, nil) -> x
merge(nil, y) -> y
merge(++(x, y), ++(u, v)) -> ++(x, merge(y, ++(u, v)))
merge(++(x, y), ++(u, v)) -> ++(u, merge(++(x, y), v))
Using the Dependency Graph resulted in no new DP problems.
