what about a one bot challenge. Everything defaulted to 1s with mega high mutations, and lots of starting energy.
A starting bot of all ones is essentially the same as one with all 0's. They have the exact same entropy. If you want to start from all 1's, that is fine for the challenge but in practice will be no different than one with all 0's.
You are welcome to tweak the mutation rate to whatever you want but you will find that too high a mutation rate is counter productive. Benificial mutations will be destroyed before they can fixate.
Start with whatever nrg you want. Use sheparad bots to supply additional nrg. Make them all veggies if you want. Each is legal for the challenge.
