Finally, the resulting skill ratings of all the contestants are saved in data/codeforces/ratings_output.csv. If a contest is not already stored in cache/codeforces/, then it is downloaded there via the Codeforces online API. It pulls data from the Codeforces contests specified in data/codeforces/contest_ids.json. Try mmr-fast for an approximate version that runs faster.Ĭodeforces is a command-line argument specifying the dataset.Īn optional integer argument may follow, to specify how many contests to process. Mmr is a command-line argument specifying the rating system. bin rate selects the entry-point multi-skill/src/bin/rate.rs. release creates a release build, which takes longer to compile but executes faster than a dev build. RUST_LOG=debug prints additional information to the terminal during execution.Ĭargo run compiles and runs a Rust project. RUST_LOG=debug cargo run -release -bin rate file. From the multi-skill/ directory, run the command Note: in theory, Elo-MMR can be applied in team competitions as well, but additional research is needed to determine the best ways to do this. Robust Response: one very bad (or very good) event cannot change your rating too much. Incentive-Compatible: the better you do in competitions, the higher your rating will be. Massively Multiplayer: the algorithm is fast and numerically stable, even with thousands or millions of individually ranked contestants. Three properties of Elo-MMR make it particularly well-suited to these aims: Ratings could be used to track a player's progress over a training programme, set motivational objectives, predict likely champions, or create invitational beginner-only or expert-only events. In these settings, it's often useful to quantify how good a player is. The contestants interact heavily with others at the same event, as in most board games. The contestants are evaluated relative to others at the same event, perhaps by a panel of judges with some degree of subjectivity, as in competitive ballroom, figure skating, and gymnastics. The Elo-MMR algorithm was designed for activities in which moderate to large numbers of players are ranked at competitive events, and results cannot be standardized across different events for any of the following reasons:Įach event features novel challenges, such as in obstacle course races, rock climbing, and academic olympiads. Rating systems estimate the skills of players who participate in a common activity.
