In computer science, a search algorithm is an algorithm that takes a problem and returns a result is a solution to the problem is, usually after weigh a variety of solutions have card. Most algorithms are studied by computer scientists to solve the problem are the search algorithm. Gather all the possible solutions to a problem called the search space. Trial and error algorithm (brute-force search) or search algorithms "rudimentary" no information to use the simplest method and the most intuitive. Meanwhile, the search algorithm uses heuristics information to apply the knowledge of the structure of the search space in order to reduce the time required for the search.
