On the convergence of the Elo rating system for a Bernoulli model and round-robin tournaments
Résumé
This report deals with limit properties of the Elo rating system. It is commonly believed that 30 games are enough to accurately rank a player but it is not always the case [1]. The Bernoulli model is first presented for 2 players. Then we'll study the N > 2 players case by numerically simulating Round-robin tournaments between the players. In all the case the Elo rating system correctly sorts people's strength.
