After all that happens, everyone who competed (in your division) is ordered by how many points they (still) have. There's a ridiculously complicated [algorithm] which then updates everyone's ratings under the general sense that everyone has some level of ability and a level of volatility, and their level of performance in any match is a random normally distributed variable with a mean of their ability and a standard deviation of their volatily. It's kind of like Elo's system with the idea that not everyone's standard deviation is the same. The main gist of the rating formula is that every match you have some expected ranking that depends on who else is competing, and if you rank better than that, your rating goes up, and if you rank worse than that, your rating goes down. -- Kawigi
Different point, [this contest] is going on from yesterday (January 17th, 2007) to the 31st, and might be of higher-than-average interest to Robocoders. -- Kawigi
