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.

Polynomial 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))


Additionally, the following rules can be oriented:

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


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

resulting in one new DP problem.

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.
