Term Rewriting System R:
[x, y]
f(x, y) -> g(x, y)
g(h(x), y) -> h(f(x, y))
g(h(x), y) -> h(g(x, y))

     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

F(x, y) -> G(x, y)
G(h(x), y) -> F(x, y)
G(h(x), y) -> G(x, y)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Polynomial Ordering


Dependency Pairs:

G(h(x), y) -> G(x, y)
G(h(x), y) -> F(x, y)
F(x, y) -> G(x, y)


Rules:


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





The following dependency pairs can be strictly oriented:

G(h(x), y) -> G(x, y)
G(h(x), y) -> F(x, y)


Additionally, the following rules can be oriented:

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


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(g(x1, x2))=  x1  
  POL(G(x1, x2))=  x1  
  POL(h(x1))=  1 + x1  
  POL(f(x1, x2))=  x1  
  POL(F(x1, x2))=  x1  

resulting in one new DP problem.

           →DP Problem 2
             ↳Dependency Graph


Dependency Pair:

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


Rules:


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





Using the Dependency Graph resulted in no new DP problems.
