   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

:'(:(x, y), z) -> :'(x, :(y, z))
:'(:(x, y), z) -> :'(y, z)
:'(+(x, y), z) -> :'(x, z)
:'(+(x, y), z) -> :'(y, z)
:'(z, +(x, f(y))) -> :'(g(z, y), +(x, a))

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pairs:

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


Rules:


:(:(x, y), z) -> :(x, :(y, z))
:(+(x, y), z) -> +(:(x, z), :(y, z))
:(z, +(x, f(y))) -> :(g(z, y), +(x, a))


Strategy:

innermost




The following dependency pairs can be strictly oriented:

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


There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
resulting in one new DP problem.
Used Argument Filtering System:
:'(x1, x2) -> :'(x1, x2)
:(x1, x2) -> :(x1, x2)
+(x1, x2) -> +(x1, x2)

Using the Dependency Graph resulted in no new DP problems.
