Can someone tell me how the Super Memo spaced repetition algorithms (http://www.supermemo.com/english/algsm11.htm) were calculated?
How does someone go about designing algorithms like this?
Is there a particular branch of mathematics that deals with this type of issue?
I understand the logic of the different variables and why they are included in the algorithm, but not how these elements are formed into a single unit.
I'm interested in it and would like to do some reading on the subject.
Thanks for any help
