but bringing it back to DBs dna. i think it's unlikely to see interesting group behaviour if bot pop is under 200ish. or atleast what needs to happen is you have to create several stable populations of bots, then allow them to become adapted to their environment; seperate from the other populations (also their environment should be different, maybe different shapes) then i think some group selection may occur. i realise this can be hard.
My thought as well. I think that's what made internet mode so interesting in its heyday.
For group selection (or altruism) to occur in DB there has to be a benefit in cooperation. Tieing and sharenrg avoids movement cost and is about as exciting as it gets.
Farming veggies could be an option if you can get rid of R selection. Maybe reversing the nrg ratio of -1 and -6 shots, in combination with per body squared energy for veggies.
