Glicko Rating
In 1995, Mark E. Glickman? developed the Glicko rating system to address (and solve) the problem, that the Elo rating system neglects the reliability of a player's rating.
The Glicko rating system is used on the Free Internet Chess Server (FICS) and was soon adopted by international game associations and by several internet game servers.
