   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

APP(app(plus, app(s, x)), y) -> APP(s, app(app(plus, x), y))
APP(app(plus, app(s, x)), y) -> APP(app(plus, x), y)
APP(app(plus, app(s, x)), y) -> APP(plus, x)
APP(app(app(curry, f), x), y) -> APP(app(f, x), y)
APP(app(app(curry, f), x), y) -> APP(f, x)
ADD -> APP(curry, plus)

Furthermore, R contains one SCC.

         ↳Argument Filtering and Ordering


Dependency Pairs:

APP(app(app(curry, f), x), y) -> APP(f, x)
APP(app(app(curry, f), x), y) -> APP(app(f, x), y)
APP(app(plus, app(s, x)), y) -> APP(app(plus, x), y)


Rules:


app(app(plus, 0), y) -> y
app(app(plus, app(s, x)), y) -> app(s, app(app(plus, x), y))
app(app(app(curry, f), x), y) -> app(app(f, x), y)
add -> app(curry, plus)





The following dependency pairs can be strictly oriented:

APP(app(app(curry, f), x), y) -> APP(f, x)
APP(app(app(curry, f), x), y) -> APP(app(f, x), y)


The following rules can be oriented:

app(app(plus, 0), y) -> y
app(app(plus, app(s, x)), y) -> app(s, app(app(plus, x), y))
app(app(app(curry, f), x), y) -> app(app(f, x), y)
add -> app(curry, plus)


Used ordering: Polynomial ordering with Polynomial interpretation:
  POL(plus)=  0  
  POL(0)=  1  
  POL(curry)=  1  
  POL(s)=  0  
  POL(APP(x1, x2))=  1 + x1 + x2  
  POL(app(x1, x2))=  x1 + x2  
  POL(add)=  1  

resulting in one new DP problem.
Used Argument Filtering System:
APP(x1, x2) -> APP(x1, x2)
app(x1, x2) -> app(x1, x2)
add -> add
