Webb5 nov. 2016 · 1 Answer Sorted by: 0 You need to emphasize the continuity. That is, you need to show that the set of continuous functions is nonempty and that it is closed under the operations of R [ 0, 1]. When you take the zero function, you need to note that this function is in fact continuous. WebbA common complaint with the standard SM-2 algorithm is that repeated failings of a card cause the card to get stuck in "low interval hell". In Anki, the initial acquisition process does not influence a card’s ease. You can also check out sched.py and schedv2.py in Anki’s source code for the scheduling code.
