The scientist who were talking to me, who work on the DNA RNA stuff. What difference does it make. they were arguing on a forum.

I'm not sure what you mean by that. Scientists don't tend to "believe" that the universe is random (if that were the case science couldn't exist), however, there are certain things that appear to behave randomly. Maybe this is purely a lack of understanding on our part, or there are minute scales at which randomness is a reality. Either way, randomness and probability are certainly accepted by scientists as a part of reality; as we currently understand it. There is no contradiction, the macro- and quantum-world can be different.

So you're saying scientists generally don't believe in randomness because someone on a forum told you? Right...

Yeah.... without wanting to sound patronizing, take everything you read on forums with a pinch of salt... including this one. No one here is a scientist (well okay maybe there is but you never know).

Uncertainty and probability is an integral part of our universe, it's a modern discovery(last 100 years) and it would not surprise me if biologists are not familiar with quantum theory

Man, this thing really slows down progress after awhile. 2 more days since I last checked it and I've only gotten another 100 generations. Think I'll call it quits now.

Is it just because more cars are surviving for longer?

My friend has up to generation 3400 and his cars still haven't broken 180 meters. He's running with a 1% mutation rate and 2 elite clones.

I think the lower the mutation rate, the more reliable the evolution becomes, however it becomes slower. Of course, zero mutation yields really no evolution at all, so meh.

This is a bit misleading on the coder's part because mutations do occur at 0%.
I presume he is doing something like if rnd(99) <= m... where m is the mutation probability. I don't know why he would add an equals instead of if rnd(99) < m... but hey, I'm running it right now on 0% and they are evolving.

[edit] I'm running on 0% with 0 elite clones to see what happens.

Update:

It has run just barely over 3,000 generations, and 195 meters is still the farthest any car has gotten. Furthermore, that record was achieved by a car from around generation 1,000. I have no reason the stop the simulation though, so keep going it shall!
