Lol... and of course I completely forgot I left this running. But here are the results at a 10% mutation and 9 hours to work at it: The designs are definitely more interesting than when I left this morning. The sad part though is that a lot of the cars being spawned now still can't climb the same steep slope in the middle of the race. I can see from the records though that a number of cars had gotten past that slope while I was gone. Genetic algorithms are sweet and if the problem set is well formed can be very effective. This is a really interesting application. Thanks for the share kleinbl00
Just for completeness here is my winner. I figured out how to replay your best car. Unique properties that I noticed about this car. It has big wheels able to get it over the steepest hills. It's very difficult for it to get stuck when it rolls over. In fact it cleared many of the hills by repeatedly going at it, flipping over, regaining speed, and ultimately climbing it.
