Basically, what Rich is saying, is, the way a scene is made is always different. If you'll look at my Algobox account, you'll notice there's a scene that's just one box and a plane. However, that scene would be considered "good," since it aided myself and some other people in new technologies in Algodoo. Now look at some of those crap scenes made by other people, with way more objects, hinges with motors, things like that. It has much more than my scene, but many people think it's "bad."
Now here's the problem: The computer thinks my scene is good, and that the other scene is bad. It now thinks that basically all scenes with a single box are good, and all scenes with hinges and motors and things are bad. Then to make things even
more complicated, someone rates a scene with one box
bad. Now the computer doesn't know what to think. It'll be stuck somewhere in the middle. Eventually, more single-box scenes get a bad rating, and my useful one is removed.
Now, remember that other example I gave, with the crappy scene? Well there are other scenes with motors and polygons, and a lot of objects, except these ones are actually
good. The computer will think that even the crappy scenes are good, therefor, making this idea counterproductive. It'll delete simple-but-good scenes, while letter complex-but-bad ones through, which is the opposite of what we want.
Therefor, this is a bad idea, and it would also require way too much time and effort, plus the need for an extremely strong supercomputer that can rate that many scenes at once all day, 24/7.
So... anyone read I, Robot?
