A search algorithm looks for an object satisfying a specified condition within a collection or state space. Linear search inspects entries directly; binary search exploits sorted order; breadth-first search explores graph states by distance from a start. The specification should say whether to return one witness, every witness or proof of absence. A procedure that eventually finds every reachable witness may still fail to terminate when none exists in an infinite space. Representation and available structure determine which candidates can safely be ruled out without inspection.
A search algorithm is a method used to retrieve information stored within some data structure or to find a specific solution to a problem. It involves systematically exploring a collection of possibilities to locate a desired outcome. Search algorithms are fundamental in computer science and are used in various applications, such as databases, artificial intelligence, and optimization. There are two primary categories of search algorithms: 1. **Uninformed Search Algorithms**: These algorithms do not have additional information about the problem apart from the problem definition.
