[FEAT] Port a modern spaced repetition algorithm into obsidian-spaced-repetition plugin

[L-M-Sherlock]

Is your feature request related to a problem? Please describe. The SM-2 algorithm is inflexible and out of date. It couldn't fit each user's memory.

Describe the solution you'd like I have published a paper to propose a modern spaced repetition algorithm at ACM SIGKDD. Here is the free access version https://www.maimemo.com/paper/

Meanwhile, I have implemented it in Anki as a custom scheduling at https://github.com/open-spaced-repetition/fsrs4anki

I guess it is not too hard to port it into obsidian.

Additional context By the way, I am helping RemNote's developers to upgrade their scheduler.

Is your feature request related to a problem? Please describe. The SM-2 algorithm is inflexible and out of date，Algorithms need to be provided that can be chosen by people。

Describe the solution you'd like A friend of mine is also an expert on spaced repetition algorithms and has published a paper at ACM SIGKDD proposing a modern spaced repetition algorithm. Here is the free access version https://www.maimemo.com/paper/ Additional context Both Remnote and Anki already support the new algorithm, and I hope your plugin will support it too.

Hi, thanks! I'm looking into implementing this as well

It's likely out of scope for this change, but it'd be great to be able to select different scheduling algorithms on a deck-by-deck basis. My use case would be to use a priority based scheduling algorithm for some decks to implement an incremental reading workflow rather than relying on the unmaintained https://github.com/bjsi/incremental-writing plugin.

I find that this issue is inactive for a long time. Do you encounter any problems? The community contributor refactored the JavaScript package of FSRS here: https://github.com/open-spaced-repetition/fsrs.js

Maybe it would be helpful to you.

Hello @L-M-Sherlock, the link to the article now redirects to paywalled page. Can you provide another link?

I tested it and it is still free access. Maybe you need to use another browser?

Thanks, it was indeed the browser, worked in Brave.

Is opening a PR here about this port something that makes sense? It seems good to me to unify the repos to continue with single implementation and fixes
