I would like to understand this spaced repetition algorithm, but it looks very mathematical to me -which is not my field at all. However, I would like to dive into it.
My question: What are the concepts involved in this algorithm that I would need to study, before I can understand it? I am not looking for a shopping list or book recommendations, but just the areas & subjects areas you think I should cover in order to tackle this algorithm. What's involved there?
Also, do let me know if you think this is a very complex endeavour, or if, quite the opposite, I could maybe just sit down with a mathematician who can explain this to me in plain English - I have no idea if it actually is as complex as it looks like to me, a complete beginner.
PS: Being a beginner, i am not entirely sure what to tag here, if somebody could help me out that would be greatly appreciated!
