- 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
- algorithm - Peak signal detection in realtime timeseries data - Stack . . .
Robust peak detection algorithm (using z-scores) I came up with an algorithm that works very well for these types of datasets It is based on the principle of dispersion: if a new datapoint is a given x number of standard deviations away from a moving mean, the algorithm gives a signal The algorithm is very robust because it constructs a separate moving mean and deviation, such that previous
- algorithm - What is the difference between depth and height in a tree . . .
This is a simple question from algorithms theory The difference between them is that in one case you count number of nodes and in other number of edges on the shortest path between root and concrete
- 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
- What is Sliding Window Algorithm? Examples? - Stack Overflow
While solving a geometry problem, I came across an approach called Sliding Window Algorithm Couldn't really find any study material details on it What is the algorithm about?
- Circle line-segment collision detection algorithm? - Stack Overflow
I have a line from A to B and a circle positioned at C with the radius R What is a good algorithm to use to check whether the line intersects the circle? And at what coordinate along the circles
