     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

APP(app(apply, f), x) -> APP(f, x)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation Transformation


Dependency Pair:

APP(app(apply, f), x) -> APP(f, x)


Rule:


app(app(apply, f), x) -> app(f, x)


Strategy:

innermost




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

APP(app(apply, f), x) -> APP(f, x)
one new Dependency Pair is created:

APP(app(apply, app(apply, f'')), x'') -> APP(app(apply, f''), x'')

The transformation is resulting in one new DP problem:

     ↳DPs
       →DP Problem 1
         ↳FwdInst
           →DP Problem 2
             ↳Polynomial Ordering


Dependency Pair:

APP(app(apply, app(apply, f'')), x'') -> APP(app(apply, f''), x'')


Rule:


app(app(apply, f), x) -> app(f, x)


Strategy:

innermost




The following dependency pair can be strictly oriented:

APP(app(apply, app(apply, f'')), x'') -> APP(app(apply, f''), x'')


Additionally, the following usable rule for innermost w.r.t. to the implicit AFS can be oriented:

app(app(apply, f), x) -> app(f, x)


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(apply)=  0  
  POL(app(x1, x2))=  1 + x2  
  POL(APP(x1, x2))=  1 + x1  

resulting in one new DP problem.

Dependency Pair:


Rule:


app(app(apply, f), x) -> app(f, x)


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
