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.

Argument Filtering and Ordering


Dependency Pair:

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


Rule:


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


Strategy:

innermost




The following dependency pair can be strictly oriented:

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


There are no usable rules for innermost that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(g(x1))=  1 + x1  
  POL(F(x1))=  x1  

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

Dependency Graph


Dependency Pair:


Rule:


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


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
