A python library for the Elo Rating System. Right now it only supports 1 vs 1 games.
- The Elo Rating System (Elo) is a rating system used for rating players in games. Originally developed for chess by Arpad Elo, Elo has been applied to a large array of games.
- Each player is assigned a number as a rating. The system predicts the outcome of a match between two players by using an expected score formula (i.e. a player whose rating is 100 points greater than their opponent's is expected to win 64% of the time).
- Everytime a game is played, the Elo rating of the participants change depending on the outcome and the expected outcome. The winner takes points from the loser; the amount is determined by the players' scores and ratings
- A win is counts as a score of 1, loss is a score of 0, and draw is a score of 0.5
