Already fixed the mutation history bug in the new version.
The main problem with Nuking zero bots is that:
Even though they do evolve to some what move reproduce and eat, they are too unstable to sustain this ability. I would of loved to use this method in my experiments, but I have no way to programmaticy determine when a robot has all three abilitys. It is like looking for a needle in a hay stack where the needle will eventually warp back into hay. However, you got me thinking about using this method. Did you make all the robots veg, or your starting population is over 100 robots, or both?
