Breadth-first search (BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level. Extra memory, usually a queue, is needed to keep track of the child nodes that were encountered but not yet explored. WebOct 7, 2024 · Here are the steps to a Breadth-first search process: There is a start vertex S. Initialize a set for level with start vertex S as level 1. Explore which other vertex is reachable from the start. Those vertices will be considered as level 2. In this way, vertices will be opened level by level.
