ChaosCraftAI

ChaosCraft is an experiment in Genetic Learning algorithms in an attempt to evolve neural networks to control bots in Minecraft. In order for a bot to survive they must fulfill various fitness functions such as digging, placing blocks and crafting. If they survive long enough their neural network(brain) will be copied into children bots and some additional neurons will be added. On a long enough timeline this hopefully will render some interesting complex and unexpected behaviors. This could be applied to other games creating unexpected behavior from the AIs and a unique gameplay experience every time for the player.
