The TRS R consists of the following rules:

app2(app2(minus, x), 0) -> x
app2(app2(minus, app2(s, x)), app2(s, y)) -> app2(app2(minus, x), y)
app2(app2(quot, 0), app2(s, y)) -> 0
app2(app2(quot, app2(s, x)), app2(s, y)) -> app2(s, app2(app2(quot, app2(app2(minus, x), y)), app2(s, y)))
app2(app2(plus, 0), y) -> y
app2(app2(plus, app2(s, x)), y) -> app2(s, app2(app2(plus, x), y))
app2(app2(plus, app2(app2(minus, x), app2(s, 0))), app2(app2(minus, y), app2(s, app2(s, z)))) -> app2(app2(plus, app2(app2(minus, y), app2(s, app2(s, z)))), app2(app2(minus, x), app2(s, 0)))
app2(app2(plus, app2(app2(plus, x), app2(s, 0))), app2(app2(plus, y), app2(s, app2(s, z)))) -> app2(app2(plus, app2(app2(plus, y), app2(s, app2(s, z)))), app2(app2(plus, x), app2(s, 0)))
app2(app2(map, f), nil) -> nil
app2(app2(map, f), app2(app2(cons, x), xs)) -> app2(app2(cons, app2(f, x)), app2(app2(map, f), xs))
app2(app2(filter, f), nil) -> nil

app2(app2(app2(app2(filter2, false), f), x), xs) -> app2(app2(filter, f), xs)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
