#3So boxcar2d, but without flash.

#4> evolve random two-wheeled shapes into cars over generations
Where I come from, we call two-wheeled automobiles motorbikes. Very cool simulation though!

#5Btw, how much AI goes into designing the exterior of a car (panels, lights, windows, grill) ? Can they just drag a slider for "How much muscle do you want" from "Yes" to "Beige" ?

Very little. It's heavily computer aided, but the overall design is largely done by humans with some marginal input by engineers for annoying realities like aerodynamics and sensors.

#7Why are the cars so spiky and why do they stay that way? Mostly what I saw was the wheels move and change size.

I knew I had seen something like this over a decade ago!

#9this is fun, even though the speed controls aren't super intuitive. You can press "Surprise" to speed things up and go through a bunch of iterations quickly.
The mutation rate (likelihood that g changes) and mutation size (Δg) are fun hyperparameters to tweak while watching the population evolve over time.
It would be interesting to see a gene for "compliance" so the cars could have some kind of suspension. EVerything more or less evolved into a sort of tron-bike shape for most of the runs I tried.

#10Interesting. Is there a way to do this in a 3d physics based simulation environment. It would be cool to see if a genetic algorithm could be used to discover new aerodynamic configurations for drones/other platforms in simulation.
I don't know enough about genetic algorithms to say for certain. Anyone have any reference materials for someone that's just started looking into this?
