We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

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)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.
APP(x1, x2) = APP(x2)
app(x1, x2) = app(x1, x2)
map = map
cons = cons

Recursive path order with status [2].
Precedence:

map > app₂ > APP₁
cons > APP₁

Status:

APP₁: multiset
map: multiset
app₂: multiset
cons: multiset

The following usable rules [14] were oriented: none
