`     ↳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.

`     ↳DPs`
`       →DP Problem 1`
`         ↳Argument Filtering and 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))

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))

The following usable rule w.r.t. to the AFS can be oriented:

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

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

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

Using the Dependency Graph resulted in no new DP problems.
