BFS walks through all nodes on the current level before moving on to the next level .

WebApr 2, 2024 · Breadth-First Search is a graph traversal algorithm that explores all the vertices of a graph in breadth-first order. This means that BFS visits all the neighbors of a vertex before exploring the neighbors of the neighbors. In other words, BFS traverses the graph in layers, starting from the source vertex and moving outwards. ... WebBreadth-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 …
