The "Free Spaced Repetition Scheduler" algorithm is a machine learning based algorithm used for determing the best interval spacing for flashcards that is individually trained from a user's historical time-series review data for a specific deck. It outperforms all existing algorithms, including the most recent iteration of Piotr Wozniak's Closed source SuperMemo algorithm, and is slated to be integrated natively into Anki in the near future.
