I don't see how any system could prevent this.
This can be done relatively easily using network algorithms. Essentially your throttle how much of a contribution each other player can make to a player's rank. This throttling would probably be done relative difference in the rank between players and the square of the size of the pool of players. Such a metric would actually benefit all players, by encouraging them to play as many different other players as possible and avoid the formation of player cliques. One would have to ensure that you weren't penalising player who always played at a certain time of day in a certain timezone, however. cheers stuart _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
