glickorank

A simple implementation of the Glicko-2 rating system.

Input is on stdin and output is on stdout.

Ratings are of the form:

   [timestamp] [game/class] [rating] [player] rd=[ratingdeviation] v=[volatility]

Match results are of the form:

   [timestamp] [game/class] [1-0/0-1/1-1] [player1] [player2]

Input consists of an optional section of pre-existing ratings, followed by a section of match results.

Output consists of ratings.

The game/class feature allows one to track several parallel games at once; for instance chess and go, or different game modes in a video game. At any rate, the ratings for the different game classes will be completely independent.
