Search engine indexing algorithm. License. MIT License. Website. bitfunnel .org. BitFunnel is the search engine indexing algorithm and a set of components used in the Bing search engine, [1] which were made open source in 2016. [2] BitFunnel uses bit-sliced signatures instead of an inverted index in an attempt to reduce operations cost.
MassMatrix is a database search algorithm for tandem mass spectrometric data. It uses a mass accuracy-sensitive, probabilistic scoring model to rank peptide and protein matches. MassWiz Open source: MassWiz is a search algorithm developed at the Institute of Genomics and Integrative Biology that can be used as a Windows command-line tool.
In computer science, a search algorithm is an algorithm designed to solve a search problem. Search algorithms work to retrieve information stored within particular data structure, or calculated in the search space of a problem domain, with either discrete or continuous values . Although search engines use search algorithms, they belong to the ...
In computer science, a trie ( / ˈtraɪ /, / ˈtriː / ), also called digital tree or prefix tree, [ 1] is a type of k -ary search tree, a tree data structure used for locating specific keys from within a set. These keys are most often strings, with links between nodes defined not by the entire key, but by individual characters.
Search data structure. In computer science, a search data structure[citation needed] is any data structure that allows the efficient retrieval of specific items from a set of items, such as a specific record from a database . The simplest, most general, and least efficient search structure is merely an unordered sequential list of all the items.
Binary search Visualization of the binary search algorithm where 7 is the target value Class Search algorithm Data structure Array Worst-case performance O (log n) Best-case performance O (1) Average performance O (log n) Worst-case space complexity O (1) Optimal Yes In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search ...
Grover's algorithm. In quantum computing, Grover's algorithm, also known as the quantum search algorithm, is a quantum algorithm for unstructured search that finds with high probability the unique input to a black box function that produces a particular output value, using just evaluations of the function, where is the size of the function's ...
Okapi BM25. In information retrieval, Okapi BM25 ( BM is an abbreviation of best matching) is a ranking function used by search engines to estimate the relevance of documents to a given search query. It is based on the probabilistic retrieval framework developed in the 1970s and 1980s by Stephen E. Robertson, Karen Spärck Jones, and others.
