   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pairs:

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


Rule:


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





The following dependency pair can be strictly oriented:

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


The following usable rule using the Ce-refinement can be oriented:

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


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(.(x1, x2))=  1 + x1 + x2  
  POL(.'(x1, x2))=  1 + x1 + x2  

resulting in one new DP problem.
Used Argument Filtering System:
.'(x1, x2) -> .'(x1, x2)
.(x1, x2) -> .(x1, x2)

Dependency Pair:


Rule:


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





Using the Dependency Graph resulted in no new DP problems.
