#28 Add Spaced Repetition Flashcard Algorithm

[Anonymous]

This program would be perfect if it incorporated some sort of spaced repetition in which new problems are treated like flash cards using a technique like supermemo, fullrecall, vtrain, or memory lifter. The idea is that when you are learning something new, you'll forget it at a certain rate, and taking advantage of that rate you can avoid repeating material that you know well and focus on material you need to review or learn.
