My first ever full bot, pretty basic but an ok search pattern.

Newbie / Evolution

« on: October 13, 2007, 06:23:40 PM »

I'm trying to create a bot that decides whether or not to attack the target based on the target's strength - perhaps a bit advanced, but I like to jump right into things.

Maybe I should give details on what I'm trying to do: the bot seeks out other bots. It eats vegetables if it finds them. If it finds a member of its own species, it checks its strength. If it's weak, it eats it, if not it leaves it alone. It does the reverse to different-species bots (eats the strong, leaves the weak). The idea is that in this way, the bot not only perpetuates beneficial natural selection within it's own species, but also prevents other species from evolving beneficial traits.

So I'd like to know more on evolution in DB. How does DNA change from generation to generation? If I understand correctly it only works with spontaneous mutations, and the mutants who are stronger reproduce more, like in real life. But, for example, how complex can these mutations be? Are they just minor changes to genes, or can genes get deleted or entirely new ones added?

Additionally: do different species deal different amounts of damage with their shots; and do different species have different amounts of max energy/velocity? And if so, can these values change over the generations?

Thanks.

Oh, and while I'm at it -- what's a Zero Bot?
