Termination of R to be shown.

Dependency Pair Analysis



R contains the following Dependency Pairs:

F(g(x)) -> F(a(g(g(f(x))), g(f(x))))
F(g(x)) -> F(x)

Furthermore, R contains one SCC.

Polynomial Ordering


Dependency Pair:

F(g(x)) -> F(x)


Rule:


f(g(x)) -> f(a(g(g(f(x))), g(f(x))))





The following dependency pair can be strictly oriented:

F(g(x)) -> F(x)


Additionally, the following rule can be oriented:

f(g(x)) -> f(a(g(g(f(x))), g(f(x))))


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

resulting in one new DP problem.

Dependency Graph


Dependency Pair:


Rule:


f(g(x)) -> f(a(g(g(f(x))), g(f(x))))





Using the Dependency Graph resulted in no new DP problems.
