I am running the simulated car racing competition for CIG 2007. The problem is a bit different from the versions of the car racing problem we've been exploring so far in that there are no walls, and the next two waypoints are visible to the controller. But there are similarities as well - in fact, quite a bit of the simulation code is reused from my earlier experiments...
Please consider taking part in the competition - the final rules are not online yet (will be really soon, promise), but the code is there for you to start playing around with. It will be really interesting to see what sort of controller the winner will be - hand-coded? Evolved neural network? Fuzzy logic? Genetic programming? Learned through temporal difference learning? Something completely different? (Probably it will be some sort of hybrid of man and machine efforts. Hybrids always win in the end.)
So, off you go. Have a look at the competition, and start designing your controllers.
Yes, I mean you.
