--- Quote from: Numsgil ---Competition requires action.  If your zerobots don't yet do anything, then there's no natural selection and it's all the same.  Once you get a zerobot that can reproduce, it'll create its own competition.  So for the purposes of zerobots, 1000 bots or 1 bot, it's essentially the same.

Even without competition, my intuition tells me it is not the same. I don't have the (insight in the) math, but to me a simple example is the following: in sequential mutations a negative mutation has to be undone and positive mutations have to occur, whereas in parallel mutatin the negatives don't have to be undone.

Lyndon:
My zerobot did reproduce (3 times) but it lost its reproduction gene, surely the new bots will cause some sort of competition and since they are already thoroughly mutated they should themselves find a way to reproduce more quickly than the first.

In zerobot sims it is often just waiting till one reproduces. That way it is still the very same.

He lost it, did you have high mutation rates.

Lyndon:
Yes high rates.

ikke:
If you have too high rates your bot will mutate more often than it reproduces. This effectively allows your species genome to degrade, by accumulating random mutations. Lower it. My sim has about 400 bots and a default mutation rate. Evolution is about patience. If you have the reproducing genome you may want to restart a sim with more specimen of the same species.
