Numerical Recipes' two chapters on FT (one on implementation, one on applications) is a longer introduction. It does especially well at addressing Confusion's point by making FTs' meaning intuitive, across many domains. http://www.amazo

This would give you the maximum weighted item, but not a weighted probability distribution.

Here's a sampling algorithm that will work, as long as the maximum weight isn't too much greater than the average weight: 1) Determine the maximum weight mw. (This is O(N) the first time, O(K) subsequent times.) 2) Repeat until an index i

"And why Python, then? Well, said Sussman, it probably just had a library already implemented for the robotics interface, that was all." I can confirm this is true. The Python Robotics module (Pyro) inspired MIT's internal library, SoaR, w

If your capacity requirements are very steady, you could save more than 30% on CPU time with this. At the very least, figure out how many instances you need at 3am and buy that many reservations. That's what I'll be doing tomorrow.
