comment Hypothesis testing: does Program $1$ play a game better than Program $2$
It sounds like a binomial distribution, I agree. I'm unclear on how the "branching factor" or the fact that each game is chaotic (if you mean it is sensitively dependent on initial conditions) might matter-- what are the initial conditions? How would the results be different than the distribution from a coin flip if the games were evenly matched?

comment Hypothesis testing: does Program $1$ play a game better than Program $2$
The result of pitting one program against the other is just X wins or Y wins? They don't get scores? When you say it is "chaotic" is that implying that each iteration of this game is NOT independent from previous iterations? If they are independent then what is "chaotic" ?

comment Thinking Problem Involving Average Rate of Change
Why did you pick $t_1=0$ and $t_2=12$? How do those numbers relate to question? Most of the other things you are doing look good!

comment What is an Empty set?
Just because a concept was evident on first inspection for a few doesn't make it unworthy of discussion. I want more people to feel good about talking about mathematics. You know what I hate? The artificial sense of exclusivity some of us project onto the field. I don't mind the desire to spend time intelligently; but the notion that the questions and work of amateurs are somehow getting undeserved attention simply because they are more comprehensible or are harming "real math" that I find terribly self-destructive.

comment Find a function so whenever it is near a lattice point $\lim_{x \rightarrow [x_0]}f(x)=[y_0]$
Tommi that is the nearest integer function.

I think you have been very helpful. I didn't notice the error that you pointed out. Do you still think the question is flawed?

I did not see your comment. In any case thanks for the input. I thought your example was for all c.

That's what I wrote. But thanks for pointing this out.

$\lim_{x \rightarrow [x_0]}f(x)=[f(x_0)]$ is that better?

But what I've said is that $\lim_{x \rightarrow [x]} f(x) = [f(x)]$
