     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation Transformation


Dependency Pair:

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


Rule:


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


Strategy:

innermost




On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

F(g(X)) -> F(X)
one new Dependency Pair is created:

F(g(g(X''))) -> F(g(X''))

The transformation is resulting in one new DP problem:

       →DP Problem 1
         ↳FwdInst
           →DP Problem 2
             ↳Forward Instantiation Transformation


Dependency Pair:

F(g(g(X''))) -> F(g(X''))


Rule:


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


Strategy:

innermost




On this DP problem, a Forward Instantiation SCC transformation can be performed.
As a result of transforming the rule

F(g(g(X''))) -> F(g(X''))
one new Dependency Pair is created:

F(g(g(g(X'''')))) -> F(g(g(X'''')))

The transformation is resulting in one new DP problem:

         ↳FwdInst
           →DP Problem 2

             ...
               →DP Problem 3
                 ↳Argument Filtering and Ordering


Dependency Pair:

F(g(g(g(X'''')))) -> F(g(g(X'''')))


Rule:


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


Strategy:

innermost




The following dependency pair can be strictly oriented:

F(g(g(g(X'''')))) -> F(g(g(X'''')))


There are no usable rules for innermost that need to be oriented.
Used ordering: Homeomorphic Embedding Order with EMB
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(X)


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
