   R
     ↳Dependency Pair Analysis



R contains the following Dependency Pairs:

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

Furthermore, R contains one SCC.

     ↳DPs
       →DP Problem 1
         ↳Forward Instantiation Transformation


Dependency Pairs:

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


Rule:


app(app(app(uncurry, f), x), y) -> app(app(f, x), y)


Strategy:

innermost




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

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

APP(app(app(uncurry, app(app(uncurry, f''), x'')), x0), y) -> APP(app(app(uncurry, f''), x''), x0)

The transformation is resulting in one new DP problem:

         ↳FwdInst
           →DP Problem 2
             ↳Argument Filtering and Ordering


Dependency Pairs:

APP(app(app(uncurry, app(app(uncurry, f''), x'')), x0), y) -> APP(app(app(uncurry, f''), x''), x0)
APP(app(app(uncurry, f), x), y) -> APP(app(f, x), y)


Rule:


app(app(app(uncurry, f), x), y) -> app(app(f, x), y)


Strategy:

innermost




The following dependency pairs can be strictly oriented:

APP(app(app(uncurry, app(app(uncurry, f''), x'')), x0), y) -> APP(app(app(uncurry, f''), x''), x0)
APP(app(app(uncurry, f), x), y) -> APP(app(f, x), y)


The following usable rule for innermost can be oriented:

app(app(app(uncurry, f), x), y) -> app(app(f, x), y)


Used ordering: Lexicographic Path Order with Non-Strict Precedence with Quasi Precedence:
trivial

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

Dependency Pair:


Rule:


app(app(app(uncurry, f), x), y) -> app(app(f, x), y)


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
