   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Argument Filtering and Ordering


Dependency Pair:

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


Rules:


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


Strategy:

innermost




The following dependency pair can be strictly oriented:

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


There are no usable rules for innermost w.r.t. to the AFS that need to be oriented.
Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(h(x1))=  1 + x1  

resulting in one new DP problem.
Used Argument Filtering System:
F(x1, x2) -> x2
h(x1) -> h(x1)

             ↳Dependency Graph


Dependency Pair:


Rules:


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


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
