   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(s(x), y, y) -> F(y, x, s(x))

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pair:

F(s(x), y, y) -> F(y, x, s(x))


Rules:


g(x, y) -> x
g(x, y) -> y
f(s(x), y, y) -> f(y, x, s(x))





The following dependency pair can be strictly oriented:

F(s(x), y, y) -> F(y, x, s(x))


There are no usable rules using the Ce-refinement that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(s(x1))=  1 + x1  
  POL(F(x1, x2))=  x1 + x2  

resulting in one new DP problem.
Used Argument Filtering System:
F(x1, x2, x3) -> F(x1, x2)
s(x1) -> s(x1)

             ↳Dependency Graph


Dependency Pair:


Rules:


g(x, y) -> x
g(x, y) -> y
f(s(x), y, y) -> f(y, x, s(x))





Using the Dependency Graph resulted in no new DP problems.
