The problem seems to have the same flavor as the Collatz conjecture. Simple dynamical system - very difficult to tell what happens in the long run. Perhaps these things are too hard for (human) mathematics. I wonder if anyone has proved any

In case anyone is wondering, the way to interpet the rules is as follows. * The state of the system is a black-white assignment of colors to the grid. * The rules tell you how to compute the next state of the system. * To update the state a

Many problems can be reduced to graph coloring problems if you look at it the right way. Try understanding the standard examples (see the applications section in Wikipedia), then it is really easy to come up with your own applications.

I agree with the first 3 statements. Just to confirm, I am using 'almost surely' in the technical sense, which means 'with probability 1.' Consider the following statement: If you keep flipping a fair coin every day, it

You’re right. I made a mistake - I thought you were trying to contradict the theorem I stated. I’ve just realized you were saying something orthogonal. As for the proof of my theorem, By taking logarithms, the process becomes an additive ra

The mean converges exponentially to zero with time. It doesn’t grow exponentially. So the theorem you cited also goes in the same direction of my statement.

No matter how many test subjects you use, if you run the experiment for a very long time, everyone goes bankrupt and will never recover. More precisely there is a finite time after which no-one ever passes above $0.0000000000000001. That is

Curious, who drilled it into your head? Were you/are you a quant? I see the 'house money' fallacy all the time (most commonly in the context of 'take out your initial investment').

I did read the thread. Someone was saying how whiteboard prompts are scary and has a high false negative rate. You took that and turned it into "if you find interviews scary, that's a signal that you have unreasonable social skill

Sounds like stress doesn't impact you, even in interview settings. Good for you! Too bad it seems like you also lack the empathy to see why other people might find interviews different from normal work-collaboration duties. And no, it&

Very interesting. Do you have any suggestions for reading more about this? "It is actually one of the nice facts of life that as you dial up the local instability of a dynamical system you get a corresponding increase in the statistica

Can you explain why the lawyers needed mirror sites? Does mirroring a site mean making a local copy of it?

And then some other guy will object to your use of 'precise' or 'exact'. Just read the definition and move on.

You're right. I was 100% thinking of 'stat arb' when I wrote that comment. What I meant to say that the way 'arb' is used is completely meaningless. Maybe a clearer comment would have been: "If rentech's s

Someone said, roughly, that X should be like Y. You immediately asked them why this was ethically optimal. To me that seems like a non-sequiter. There is no reason to suspect that the optimization (with respect to whatever objective you des

Why did you automatically bring "ethics" into this discussion? The person you replied to was probably using the word 'should' in reference to some other objective.

That's because (imo) numbers aren't intrinsic to the physical universe. They are (imo) an abstraction we humans invented to describe certain phenomena. You may not agree but hopefully you can at least see why some people would hav

I don't think it's fair to characterize such people as "incapable of learning how to do new things" if they're not even being given the opportunity to learn. I'm not saying that the OP should hire these people,

That's a good point about the linguisitic connotations. faitswulff's comment reads so much better to me when you just replace the word 'privilege' with 'virtuous cycle' or 'snowball effect'.
