  Search algorithm - Wikipedia, the free encyclopedia
Brute-force search or "naïve"/uninformed search algorithms use the simplest, most intuitive method of searching through the search space, whereas informed search algorithms use heuristics to apply knowledge about the structure of the search space to try to reduce the amount of time spent searching.
The drawback is that most search spaces are extremely large, and an uninformed search (especially of a tree) will only take a reasonable amount of time for small examples.
This is a type of search which solves constraint satisfaction problems where, rather than looking for a path, the solution is simply a set of values assigned to a set of variables.

 search space
A printed dictionary may be awkward to use in order to parse such a word, but the search for an appropriate Navaho mig appears to be little different than a search done in a language in which the same information is carried by individual words.
Searching an all three axes concurrently, if it can be done, reduces the search space to something quite small.
The supposed dynamics of the search using this structure is one step to g-words, one step to length five, and one cluster intersection with that point in two-dimensional space to explore along a third axis devoted to concepts.

 CBofN - Glossary - S
For a neural network the search space is defined as all possible assignments to the network weights; for a genetic algorithm, it is every conceivable value assignment to the strings in the population.
Space Complexity A function that describes the amount of memory required for a program to run on a computer to perform a particular task.
Steepest Descent (Ascent) A search method that uses the gradient information of a search space and moves in the opposite direction from the gradient until no further downhill (or uphill) progress can be made.

 Sentence Modeling and Parsing
A derivation of a sentence according to the grammar is a path in the configuration space of the grammar from an initial configuration to a final configuration in which all the elementary constituents are consumed.
The choice of evaluation function is thus a tradeoff between reduced search space (and thus reduced runtime and memory requirements) and the risk of missing the correct analysis (or even every analysis).
Computationally, the critical property of an evaluation function is whether it is compatible with tabular algorithms for searching the derivation space, in the sense that the score of a derivation is determined by the scores of the subderivations into which the derivation is factored by tabulation.

 BBC News | WALES | Scientists search for space 'bugs'
A search for extraterrestrial bugs which may be invading Earth has been launched by British scientists.
According to some theories, life from space may have been "seeded" on Earth, and could even now be fuelling epidemics of flu and other illnesses.
In 1996 scientists at the American space agency Nasa claimed to have found the first evidence of extraterrestrial life in a Martian meteorite - a piece of Mars rock that landed on Antarctica.

 perl.com: Building a Vector Space Search Engine in Perl
Vector-space search engines use the notion of a term space, where each document is represented as a vector in a high-dimensional space.
To search our collection, we project a query into this term space and calculate the distance from the query vector to all the document vectors in turn.
This is a common problem in search engine design, so of course there is a module on the CPAN to solve it.

 A Java-example of a genetic algorithm working in two-dimensional search-space, based on genitor.
Unfortunately, most GAs run in a space with more than the three dimensions we are familiar with; often even in a space with only the two coordinates 0 and 1, but a hundredfold of dimensions.
It is well suited for fractal landscapes: The offsprings are born between parents with a high fitness (laying on high places of the landscape), which means that areas around fit bugs are investigated intensively.
First, this is done over the whole landscape, after a while the population and therefore the search is concentrated near the hills the GA already found, and where the search continues on a smaller area with higher intensity.

Initial designs for the space coronagraph, expected to be the first of the planet-hunting pair to launch, calls for a moderate-sized visible-light telescope similar to a 13-by-20-foot (4-by-6-meter) mirror currently under study.
Those other instruments are connected by a hard and fast baseline, while the TPF version is designed to be a free-flying fleet of 13-foot (4-meter) telescopes that constantly shift themselves to keep the proper orientation.
European Space Agency researchers are planning to conduct formation-flying tests with their SMART-3 technology mission in upcoming years, the results of which could prove very valuable to both the European Darwin effort and TPF as well.

Google has introduced a new "search appliance," a pizza-box size unit that contains the full Google search functionality for internal networks and intranets.
Designed to compete head-to-head with enterprise search tools offered by industry titans such as Verity and Inktomi, the Google appliance differs in that it's an integrated hardware/software product that needs comparatively little configuration to put into action.
While Google provides standard keyword analysis and other ranking methods, its PageRank--which analyzes a page's prominence against others in a categorical search to determine which is most often referred and linked to--is less valuable in the structured design of business sites or intranets.
