Newest algorithm Questions - Stack Overflow 5 replies 33 views Algorithm for selecting random representative subset based on absolute frequencies Given a long list of (unique) names, as well as an absolute frequency for each name, what is an efficient algorithm to select a random subset that is (more or less) representative of the entire list? algorithm random
how do *you* calculate approximate Big O? - Stack Overflow Most people with a degree in CS know what Big O stands for It helps us to measure how well an algorithm scales How do you calculate or approximate the complexity of your algorithms?
algorithm - What does O (log n) mean exactly? - Stack Overflow A common algorithm with O (log n) time complexity is Binary Search whose recursive relation is T (n 2) + O (1) i e at every subsequent level of the tree you divide problem into half and do constant amount of additional work
Best algorithm for efficient collision detection between objects It would be great if the algorithm also supported visibility query too, for the rendering pipeline For the sake of simplicity, assume that collision detection here is broad-phase (i e all dynamic objects are just perfect spheres)
c - Fast CRC algorithm? - Stack Overflow CRC32 algorithm is exactly what I'm looking for, but I can't use it because the table it requires is way too huge (it is for an embedded system where resources are VERY rare) So: any suggestions for a fast and slim CRC algorithm? It does not matter when collisions are a bit more probable than with the original CRC32
