   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

APP(app(app(compose, f), g), x) -> APP(f, app(g, x))
APP(app(app(compose, f), g), x) -> APP(g, x)

Furthermore, R contains one SCC. 


   R
     ↳DPs
       →DP Problem 1
         ↳Polynomial Ordering


Dependency Pairs:

APP(app(app(compose, f), g), x) -> APP(g, x)
APP(app(app(compose, f), g), x) -> APP(f, app(g, x))


Rule:


app(app(app(compose, f), g), x) -> app(f, app(g, x))


Strategy:

innermost




The following dependency pairs can be strictly oriented:

APP(app(app(compose, f), g), x) -> APP(g, x)
APP(app(app(compose, f), g), x) -> APP(f, app(g, x))


There are no usable rules for innermost w.r.t. to the implicit AFS that need to be oriented.

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

resulting in one new DP problem.

             ↳Dependency Graph


Dependency Pair:


Rule:


app(app(app(compose, f), g), x) -> app(f, app(g, x))


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
