https://www.supermemo.com/en/blog/supermemo-is-better-than-fsrs-by-far https://www.supermemo.com/en/blog/supermemo-is-better-than-f... seems to suggest that yes, it is a major improvement over SM-2, and given how critical they are of FSRS I'm happy to believe them. SM-2 to my understanding is basically the simplest possible spaced repetition algorithm - I think something like 'double the review interval if easy, otherwise multiply by some difficulty factor to reduce this interval depending on which button was clicked'.
That said, even SM-2 is probably vastly superior to just not doing SRS at all.
- asymmetric 8mo agoIsn’t the linked article claiming that SM is superior to FSRS?
- bigDinosaur 8mo agoSM is claiming that the latest versions of the SM algorithm (namely SM-19) are vastly superior to FSRS (maybe it is?). They state in contrast: We do not dismiss the work behind FSRS. It is a commendable open-source effort and a marked improvement over ancient algorithms like SM-2. For context, Anki uses SM-2's algorithm (albeit apparently heavily modified for various special cases) if FSRS is not enabled.
