Search algorithm. 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 ...
For typical interpretations of results, search is an optimization process. There is no free lunch in search if and only if the distribution on objective functions is invariant under permutation of the space of candidate solutions. [5][6][7] This condition does not hold precisely in practice, [6] but an " (almost) no free lunch" theorem suggests ...
The percentage shows the perceived importance, and the arrows represent hyperlinks. PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. It is named after both the term "web page" and co-founder Larry Page. PageRank is a way of measuring the importance of website pages.
Combinatorial search. In computer science and artificial intelligence, combinatorial search studies search algorithms for solving instances of problems that are believed to be hard in general, by efficiently exploring the usually large solution space of these instances. Combinatorial search algorithms achieve this efficiency by reducing the ...
Criticism of Google includes concern for tax avoidance, misuse and manipulation of search results, its use of others' intellectual property, concerns that its compilation of data may violate people's privacy and collaboration with the US military on Google Earth to spy on users, [1] censorship of search results and content, its cooperation with the Israeli military on Project Nimbus targeting ...
Ranking of query is one of the fundamental problems in information retrieval (IR), [1] the scientific/engineering discipline behind search engines. [2] Given a query q and a collection D of documents that match the query, the problem is to rank, that is, sort, the documents in D according to some criterion so that the "best" results appear early in the result list displayed to the user.
Filter bubble. A filter bubble or ideological frame is a state of intellectual isolation [1] that can result from personalized searches, recommendation systems, and algorithmic curation. The search results are based on information about the user, such as their location, past click-behavior, and search history. [2]
SafeSearch helps you avoid explicit content in Search results. We can't catch everything, but the filter helps keep adult content out. If you turn off SafeSearch, you may get results that contain or depict mature or sexually explicit content. By changing your SafeSearch setting to 'Off', you acknowledge that you are at least 18 years of age.
