I created a 3D environment with a = lumpy landscape, some basic physics (gravity, Newtonian motion) and = placed a target in it that'd move to a new random location if touched. = Then I allowed a population of randomly generated GAs to operate a = virtual tank within the environment, with the simple fitness function = that the more times the target was hit within a given timeframe, the = more chance that that GA's bitstring (its DNA equivalent) would get to = "breed" and its offspring would form the next generation. In generation 1 most of the drivers just sat still, or twitched about, = or span around in circles, but every now and then, by pure fluke, a = driver would hit the gas and haphazardly nail a target. This went on = for a couple more generations, but then amazingly by about the 7th or so = there'd be emergent behaviours that really surprised me - drivers that'd = hit every target while executing a series of deft manoeuvres and = handbrake turns. All this from artificial evolution alone - albeit in a = limited environment. I think the key to good AI isn't so much in worrying about the mechanics = of how a robot would reach its goal - it can be tooled up to figure that = out for itself - its how you define a complex goal or set of goals (the = fitness function) in the first place. And no, that goal does not have = to default to "kill", that's just laziness :-) kozmikreis On 27 Jan 2010, at 20:13, Matt Arnold wrote: > I have long daydreamed of an idea similar to his, to develop robotic > sensing and movement systems.
