Sure, you can make an API that accepts JSON files. What exactly do you want this library to do? If you want to implement it in Rust, the `worldrank-api` directory...

Oh if you just want MMR itself, it's not a lot of code: https://github.com/EbTech/Elo-MMR/blob/master/multi-skill/src/systems/simple_elo_mmr.rs Would you be able to translate this to your preferred language? Feel free to ask questions.

They're the same. The bigger Elo-MMR just has a bunch of (for most purposes) unnecessary features that can be turned on, like approximations that would make it run even faster.

Inactive players get a boost when the drift is above 0.5 per day? That's unexpected.

Oh hey, I just remembered something that should explain your situation (sorry I've been a bit ill). The decay feature, which I think was pioneered by Glicko, comes with a...

You can use the uncertainty-based decay too, using the same formula to update the rating for any given time. It's just that the current implementation doesn't have a way to...

@stephankokkas in that case, wouldn't the uncertainty-based approach be more suitable? That way, the display rating is temporarily lowered, but is quickly raised when the player returns. Maybe you specifically...

@stephankokkas conservative display ratings are computed by https://github.com/EbTech/Elo-MMR/blob/b513efe/multi-skill/src/systems/common/player.rs#L15, and appear in the `all_players.csv` file that's produced if you follow the README instructions. Keeping in mind the caveats I mentioned above,...

It might take me a long time to get around to this one, though I agree that it would be a great feature to have! Let's keep this request open;...

That would be sweet. I forget: is the vertex cover possible to construct from the output of Dinic/Hopcroft-Karp, or does it need a separate algorithm?
