Dependency Pair Analysis

R contains the following Dependency Pairs:

APP(app(map, f), app(app(cons, x), xs)) -> APP(app(cons, app(f, x)), app(app(map, f), xs))
APP(app(map, f), app(app(cons, x), xs)) -> APP(cons, app(f, x))
APP(app(map, f), app(app(cons, x), xs)) -> APP(f, x)
APP(app(map, f), app(app(cons, x), xs)) -> APP(app(map, f), xs)
APP(app(treemap, f), app(app(node, x), xs)) -> APP(app(node, app(f, x)), app(app(map, app(treemap, f)), xs))
APP(app(treemap, f), app(app(node, x), xs)) -> APP(node, app(f, x))
APP(app(treemap, f), app(app(node, x), xs)) -> APP(f, x)
APP(app(treemap, f), app(app(node, x), xs)) -> APP(app(map, app(treemap, f)), xs)
APP(app(treemap, f), app(app(node, x), xs)) -> APP(map, app(treemap, f))

Furthermore, R contains one SCC.

Remaining Obligation(s)

The following remains to be proven:
Dependency Pairs:

APP(app(treemap, f), app(app(node, x), xs)) -> APP(app(map, app(treemap, f)), xs)
APP(app(treemap, f), app(app(node, x), xs)) -> APP(f, x)
APP(app(treemap, f), app(app(node, x), xs)) -> APP(app(node, app(f, x)), app(app(map, app(treemap, f)), xs))
APP(app(map, f), app(app(cons, x), xs)) -> APP(app(map, f), xs)
APP(app(map, f), app(app(cons, x), xs)) -> APP(f, x)
APP(app(map, f), app(app(cons, x), xs)) -> APP(app(cons, app(f, x)), app(app(map, f), xs))

Rules:

app(app(map, f), nil) -> nil
app(app(map, f), app(app(cons, x), xs)) -> app(app(cons, app(f, x)), app(app(map, f), xs))
app(app(treemap, f), app(app(node, x), xs)) -> app(app(node, app(f, x)), app(app(map, app(treemap, f)), xs))
