About Us

Welcome to Open Tournament IO! Our website is designed to help you create, manage, and rank tournaments using the ELO ranking algorithm. Our user-friendly interface allows you to easily set up and manage your tournaments, making it simple to track your players' progress and rankings.

ELO Ranking Algorithm

The ELO ranking algorithm, named after its creator Arpad Elo, is a method for calculating the relative skill levels of players in two-player games such as chess. It works by assigning each player an ELO rating, which is updated after each game based on the outcome and the ratings of both players. The difference in ELO ratings between two players serves as a predictor of the outcome of a match.

When a player wins a game, their ELO rating increases, while the loser's rating decreases. The amount of change depends on the difference in ratings between the two players and an adjustment factor called the K-factor. In general, a higher-rated player will gain fewer points for winning against a lower-rated player, and vice versa.

JSON Data Explanation

The JSON data used in our application contains two main parts: teams and votingLog.

teams is an array of team objects with information about each team participating in the tournament, including the team's name, description, and current ELO score.

votingLog is an array of game objects with information about the games played in the tournament and the ELO scores. Each game object has details about the winner and loser teams, including their index, name, and ELO points before the game.
