We use the reduction pair processor [13].

The following pairs can be oriented strictly and are deleted.

APP(app(app(app(filter2, false), f), x), xs) → APP(app(filter, f), xs)

Used ordering: Combined order from the following AFS and order.
APP(x1, x2) = APP(x2)
app(x1, x2) = app(x1, x2)
filter2 = filter2
true = true
filter = filter
map = map
cons = cons
false = false
nil = nil
i = i
1 = 1
. = .

Lexicographic Path Order [19].
Precedence:

APP₁ > filter2 > [filter, nil] > [app₂, false] > [map, 1]
APP₁ > filter2 > cons > [app₂, false] > [map, 1]
true > [map, 1]
i > [map, 1]
. > [map, 1]
