     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(a, y) -> F(y, g(y))
F(a, y) -> G(y)

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pair:

F(a, y) -> F(y, g(y))


Rules:


f(a, y) -> f(y, g(y))
g(a) -> b
g(b) -> b





The following dependency pair can be strictly oriented:

F(a, y) -> F(y, g(y))


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

g(a) -> b
g(b) -> b


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(g)=  0  
  POL(b)=  0  
  POL(a)=  1  
  POL(F(x1, x2))=  x1 + x2  

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

             ↳Dependency Graph


Dependency Pair:


Rules:


f(a, y) -> f(y, g(y))
g(a) -> b
g(b) -> b





Using the Dependency Graph resulted in no new DP problems.
