This is about ants.
This time, there have been few ant colonies at home. I dropped a pinch of sugar and that attracted them. No surprise(although it took longer than I expected). When I stopped using the laptop and after sometime when its lying there, I noticed some ants there. I didnt understand why wud they come if sugar is also present. Later I guessed that it came for the warmth of the laptop(these days its cold), because after a while it went back to the sugar. I have no idea how it could sense the heat. smell I can understand. Or was it just a coincidence? Maybe I should try another time.
I also found that ants are nice beings than most ppl think. They are friendly. They come with me wherever I go. Few even work with me.

Note-1: I dont know the solution for this, though I have some of my own nothing-great solutions for this.
Note-2:I made complete changes to an original problem which I heard to make it simple and elegant.

There are some N fixed-length-bit-sequences(call it word) . You have to split these words into different groups(say max is G groups. N>>G) such that the maximum "difference" between two words is minimized. "difference" is the number of bit positions which differs in the 2 words. How would do u this in an ideal world where speed or memory is not an issue(this is more like a puzzle than an algo problem)? In a realistic world where time/space is an issue(this is algo-type. graphs can come handy or atleast i think)?
Another interesting question(which came to me as I write this) is what if words are being added/deleted. How to group so as to minimize the re-organization of buckets but allowing for an approximate solution initially(say u can have G+g groups). I think this is hard.
Since I cooked-up this one, if something is not clear make ur own "reasonable assumptions".
I would love to hear ur solutions.
