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
Usable Rules (Innermost)


Dependency Pair:

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


Rule:


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


Strategy:

innermost




As we are in the innermost case, we can delete all 1 non-usable-rules.

Argument Filtering and Ordering


Dependency Pair:

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


Rule:

none


Strategy:

innermost




The following dependency pair can be strictly oriented:

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


There are no usable rules w.r.t. the AFS that need to be oriented.
Used ordering: Lexicographic Path Order with 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 Graph


Dependency Pair:


Rule:

none


Strategy:

innermost




Using the Dependency Graph resulted in no new DP problems.
