OK, new approach
30-50 zerobots that survived so far with feeding only veggie and max mutation. I'll wait till population graph start rising. Then I'll lower mutation rates and wait till they learn to feed. BTW how can I see if they started to feed on their own? Then I'll swap feeder veggie with alga minimalis and wait till movement starts.
Settings are: Bang efficiency set to 10, movement cost 1, zero costs when population fall till 40, no respawn, no dynamic costs.
Thank You for answers so far
