Algorithm

A concrete, named step-by-step procedure for solving a specific computational problem, filed as that procedure rather than as the general notion of what an algorithm is. Belongs here: Binary Search, Depth-First Search, Dijkstra's Algorithm, Merge Sort and Quicksort, each a defined method with a known running time. Does not belong here: the general concept of an algorithm, filed under Foundational Concept, and a narrower named method applied within a larger algorithm or system rather than a full procedure in its own right, filed under Technique.
