AI and biological simulation seem to be pretty orthogonal fields to me. I'm not clear on why one would expect to find life simulation in an AI community or vice versa?
Because part of life simulations, at least with more complex organisms, is simulating realistic behaviour and some sort of semblance of intelligence (I'm mostly interested in learning and decision-making). For example, this articleon the brain in Creatures 3 is the kind of thing I'd love to find more of, especially in a discussion forum. Topics covered more in traditional game AI forums seem to be locomotion, path finding, crowds, etc - all interesting subjects that can of course be relevant to life simulation as well, but seemingly more about how the AI expresses itself externally as opposed to internal evolution and state. I'm looking for something with more of a focus on the latter.
But maybe I'm wrong and they have nothing to do with each other at all! I don't work with AI (directly) in my day job
