Player Ranking System

[rt]

One of the projects i'm working on has a worldwide player ranking system which keeps track of who beat who. The current version of the ranking system performs a simple loop through the player list and assigned a rank to each player based on the number of wins, ties, and losses. This information can be then displayed on the game website.

This is good enough for the time being, but i'd like to extend it so that there is a second (or perhaps third) phase where it not only depends on how many wins and losses you have, but rather who you won and lost too. This would allow for much more accurate rankings of players.

I was searching around the web for any tips on how to construct such an algorithm, and the best i could find was http://www.ggzgamingzone.org/index.php which seems to implement the exact system i want. Does anyone else have any thoughts on how i should proceed?

Thanks!
