Breadth First Search (BFS) Algorithm - Breadth First Search (BFS) algorithm traverses a graph in a breadthward motion to search a graph data structure for a node that meets a set of criteria. It uses a queue to remember the next vertex to start a search,
Breadth first search is a graph search algorithm that starts at one node and visits neighboring nodes as widely as possible before going further down any other path. This algorithm requires the use of a queue to keep track of which nodes to visit, so it might be worth your time to brush...
Standard breadth-first search (BFS) is an algorithm for finding nodes from a starting node or nodes in a graph in breadth-first order. It returns the source node or nodes that it started from, and all of the nodes visited by each search. Note Because every source node passed in leads ...

A breadth first search traversal method, visits all the successors of a visited node before visiting any successor of any of its child nodes. This is a contradiction to depth first traversal method; which visits the successor of a visited node before visiting any of its brothers, i.e., chil...
