How can I find the time complexity of an algorithm?
1. Introduction In computer science, the time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the string representing the input. 2. Big O notation The time complexity of an algorithm is commonly expressed using big O notation, which excludes coefficients and lower order terms.

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 ...

What are some algorithms for comparing how similar two strings are?
What you're looking for are called String Metric algorithms. There a significant number of them, many with similar characteristics. Among the more popular: Levenshtein Distance : The minimum number of single-character edits required to change one word into the other. Strings do not have to be the same length Hamming Distance : The number of characters that are different in two equal length ...

Algorithm for simplifying decimal to fractions - Stack Overflow
My algorithm (short explanation) To fully understand my algorithm, you need to have read the article by Ian Richards or at least understand what a Farey pair is. Furthermore, read the algorithm with comments at the end of this article. The algorithm is using a Farey pair, containing a left and a right fraction.

What's a good algorithm to generate a maze? - Stack Overflow
This algorithm results in Mazes with about as high a "river" factor as possible, with fewer but longer dead ends, and usually a very long and twisty solution. It runs quite fast, although Prim's algorithm is a bit faster.

What's the fastest algorithm for sorting a linked list?
1 As I know, the best sorting algorithm is O (n*log n), whatever the container - it's been proved that sorting in the broad sense of the word (mergesort/quicksort etc style) can't go lower. Using a linked list will not give you a better run time.

Image comparison - fast algorithm - Stack Overflow
Each algorithm is best suited for certain types of image transformations and you can take advantage of that. At the top, the fastest algorithms; at the bottom the slowest (though more accurate). You might skip the slow ones if a good match is found at the faster level. file-hash based (md5,sha1,etc) for exact duplicates

algorithm - Bellman-Ford vs Dijkstra: Under what circumstances is ...
76 After a lot of Googling, I've found that most sources say that the Dijkstra algorithm is "more efficient" than the Bellman-Ford algorithm. But under what circumstances is the Bellman-Ford algorithm better than the Dijkstra algorithm? I know "better" is a broad statement, so specifically I mean in terms of speed and also space if that applies.

Fuzzy search algorithm (approximate string matching algorithm)
The only way I can think of implementing it as a search algorithm is to perform a linear search and executing the string metric algorithm for each string and returning the strings with scores above a certain threshold.

What's the algorithm behind minesweeper generation
7 A Strong Algorithm Here is an implementation of a MineSweeper algorithm. This algorithm takes into account some conditions while generating the map, and also performs a solver algorithm to make sure that the generated map has at least one possible solution.
