BIG O, HOW DO YOU CALCULATE/APPROXIMATE IT? - STACK OVERFLOW
Dec 19, 2019 Big-O does not measure efficiency; it measures how well an algorithm scales with size (it could apply to other things than size too but that's what we likely are interested here) - … From stackoverflow.com
ALGORITHM - PEAK SIGNAL DETECTION IN REALTIME TIMESERIES DATA
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 … From stackoverflow.com
C++ - DATA COMPRESSION ALGORITHMS - STACK OVERFLOW
There are a ton of compression algorithms out there. What you need here is a lossless compression algorithm. A lossless compression algorithm compresses data such that it can be … From stackoverflow.com
C - HOW IS A CRC32 CHECKSUM CALCULATED? - STACK OVERFLOW
Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the … From stackoverflow.com
MATH - WHAT IS THE MOST EFFICIENT WAY TO CALCULATE THE LEAST …
Jul 1, 2010 The direct implementation of the classic algorithm is efficient, but there are variations that take advantage of binary arithmetic to do a little better. See Knuth 's " The Art of … From stackoverflow.com
ALGORITHM - FINDING ALL POSSIBLE COMBINATIONS OF NUMBERS TO REACH …
Jan 8, 2011 Here is a Java version which is well suited for small N and very large target sum, when complexity O(t*N) (the dynamic solution) is greater than the exponential algorithm. My … From stackoverflow.com
WHY DOES COLLECTIONS.SORT USE MERGESORT BUT ARRAYS.SORT DOES NOT?
Sep 1, 2015 Also, the documentation didn’t catch up, which shows, that it is a bad idea in general, to name an internally used algorithm in a specification, when not necessary. The … From stackoverflow.com
ALGORITHM - DIFFERENCE AND ADVANTAGES BETWEEN DIJKSTRA & A STAR
Oct 23, 2012 If I need the algorithm to run in milliseconds, when does A* become the most prominent choice. Not quite, it depends on a lot of things. If you have a decent heuristic … From stackoverflow.com
HOW DOES A 'DIFF' ALGORITHM WORK, E.G. IN VCDIFF AND DIFFMERGE?
An O(ND) Difference Algorithm and its Variations (1986, Eugene W. Myers) is a fantastic paper and you may want to start there. It includes pseudo-code and a nice visualization of the graph … From stackoverflow.com
The algorithm has the same worst case complexity as Djikstra's, but in the average case the expected runtime is linear in the size of the graph, which is much faster than the pure Dijkstra. … From stackoverflow.com
