Found on Digg:
“Once enough votes have been collected, the genetic algorithm gets to work. It picks the good images and breeds them using either mutation or crossing-over. Since the images’ genes are just trees, it is simple to cross-over two of them and produce new ones.”
It’s a nice idea, similar-but-different to what I’m planning on trying to implement one day. I’m skeptical about how well it’ll work when faced with multiple people having disparate ideas of what looks good, along with people trying to game the system a bit. But for something fun, it’s interesting. They’ve also implemented it, which is something I haven’t gotten around to yet 🙂
