Dependency Pair Analysis



R contains the following Dependency Pairs:

F(g(X)) -> F(f(X))
F(g(X)) -> F(X)

Furthermore, R contains one SCC.

DPs

Polynomial Ordering


Dependency Pairs:

F(g(X)) -> F(X)
F(g(X)) -> F(f(X))


Rules:


f(g(X)) -> g(f(f(X)))
f(h(X)) -> h(g(X))





The following dependency pairs can be strictly oriented:

F(g(X)) -> F(X)
F(g(X)) -> F(f(X))


Additionally, the following rules can be oriented:

f(g(X)) -> g(f(f(X)))
f(h(X)) -> h(g(X))


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(g(x1))=  1 + x1  
  POL(h(x1))=  0  
  POL(f(x1))=  x1  
  POL(F(x1))=  1 + x1  

resulting in one new DP problem.

Dependency Graph


Dependency Pair:


Rules:


f(g(X)) -> g(f(f(X)))
f(h(X)) -> h(g(X))





Using the Dependency Graph resulted in no new DP problems.
