comment How to get probabilities for multinomial & hypergeometric distribution ranges more quickly?
I assume you're looking for exact methods, and not inexact faster methods such as Monte Carlo simulation or a normal approximation? I also assume you're familiar with jstor.org/stable/2347220 which provides FORTRAN code to find the distribution of the maximum value (but not the minimum value) exactly (I haven't tested the code and it may actually be slower than your method).

comment Simulation with two random walkers on a lattice with periodic boundaries
You can do two checks for equality, one after each step left/right, or you can keep the directions as variables and make sure that the pre and post position of the two walkers is the same (ie, #1 left of #2 in both cases or #1 right of #2 in both cases). If you don't count that as a collision, #1 could pass #2 and continue going to infinity, no?

comment Simulation with two random walkers on a lattice with periodic boundaries
Just skimming, but: if #1 at +5 and #2 at +4, can you end up having #1 go left and #2 go right, so that #1 at +4 and #2 at +5, but #1 and #2 not equal, so your program doesn't realize the two have collided?

comment Plots of United States states with non-standard labels
code.google.com/apis/kml/documentation/us_states.kml is where I found the US one, there should be plenty for other countries, but I don't know where they are specifically.

@Yode Oh, I thought you had mislinked. The link is in a foreign language and just appears to be a random website. I didn't realize it was the problem in a different language.

Your link goes to ugly hideousness of a page. (OP)
