  A modern Anki custom scheduling based on Free Spaced Repetition Scheduler algorithm

  

In the last two weeks, I was learning the document of Anki custom scheduling and asked some questions on the Anki forum: Some problems in implementing a state-of-the-art SRS scheduler on Anki - Scheduling - Anki Forums (ankiweb.net). Then dae and RumovZ developed some features to solve my question, and I implement a simplified version of the algorithm proposed in the paper. The code is released in here: open-spaced-repetition/fsrs4anki (github.com). Does somebody want to try the custom schedule? More feedback is welcomed.

  A spaced repetition algorithm based on DSR model

  

So I checked this and it seems that there's a whole bunch of different parameters (initial difficulty, initial stability, etc), and a lot of them are constant. So the next step would be to use some kind of optimization algorithm, like gradient descent, to optimize those parameters based on user's review history, right?
