Darwinian assembly lines.

Wow.

On a similar note, genetically 'grown' soccer softbots. In actual RoboCup competition they even defeated hand-coded opponents. Check the bottom of the page for screenshots of important evolutionary moments in the growth of the team.

I asked the developer of this software what the resulting source code looked like, and he said that he couldn't follow it or figure out how it functioned. Erie, yet cool.

The company's website offers an MPG video showing the figure "evolving" from flopping over and twitching to striding effortlessly across the floor. Beautifully creepy.

Ooh! More video! This one (MPG) is the most disconcerting, showing the characters reacting to being hit, thrown, and dropped. Ow!

Seems more Lamarckian than Darwinian.

Reading that article made me feel old..

oops, wrong thread. *whistles and walks on*

That's probably true for some of the programming techniques, goethean. Genetic programming can be quite mechanistic, copying all the realities of gene exchange, crossing over, natural selection, reproductive fitness etc. Often, particularly in problems that don't aim to copy actual living species, programmers can take shortcuts, copying the idea of evolution rather than the natural mechanisms. For example, instead of rejecting the least fit and seeing who's still alive to breed (realistic), it might just take the "top five percent" of the programs and use them to "seed" the next generation.

Now the step that remains is for a computer to be able to determine it's own desirable outcome to evolve towards. That's when they can start to take over the world.

i think they already did wingy, and we're just a simulation.

You know, that would make an interesting idea for a movie.

So, folktrash, which stage of the evolutionary process are we at now?

I like how many of the videos are of the models being hit or blown up. Where are the videos of the models breakdancing? Or on a trampoline? Even the sports ones deal more with contact than the sport component.

I got the impression that it was being marketed to special-effects people, who'd be more interested in using it for things actors can't do (like get injured).

Perhaps because it is easier to program their reaction to a single, directional force than complex independent movement? Just guessing.
