comment How can I speed up the classic GA for graph coloring?
Version 8 has no GraphColor[] functionality... are you able to import the sample inputs from the website? info.univ-angers.fr/pub/porumbel/graphs I believe that you would need v8 Import to get the .col files... I can post them as compressed matrices if you need.

Thanks, see my comments to run the code in version 7.

@DanielLichtblau I'm after a fast upperbound approx algorithm to push stuff, and I'm keen on getting a GA/GP to work. I've tried others, but if a stochastic, deterministic, and annealing method works better who am I to say, just test against the benchmark...

@Mr.Wizard lol! For once, I was actually trying to have a SLOWER function to test this on...

Ok, this looks good, can you use my original example with the function: f[x_] := Total@Table[i^4, {i, x}]

@george Yes, I feel it helps to see the divisions along weeks and months... sort of a birds eye view along all the dimensions...

After gathering by the month, stacking the matrices should be easy but its not

I was almost there, but the hard part is getting the divisions right...

comment How can I export aligned equations to $\LaTeX$?
It's a Cell style. Just go to Format -> Style -> Item Numbered. It uses a CounterBox to keep track of counts.

Has anyone got this working on Mac OS X 10.8.2?

comment How to quickly calculate intersections of filled curves?
@freddaneilkline Opencllink is very dicey, even simple questions on this are difficult to answer. Not to mention he probably wants a solution that is device independent.

comment How can I regroup elements in a list into a tree based on their values?
Arbitrarily deep, that's where the trickiness of the problem lies.

comment How can I regroup elements in a list into a tree based on their values?
Yes. The elements in the input list are always in order, and at least they could always be sorted by their first element.

@LeonidShifrin how might I adapt this to WorkBench and extracting comments for a symbol from a file?

@LeonidShifrin Nice comment grabber. But I think the project of an general inline documentation utility remains a worthy goal.
