WebBreadth First Search (BFS) is an algorithm for traversing an unweighted Graph or a Tree. BFS starts with the root node and explores each adjacent node before exploring node (s) at the next level. BFS makes use of Queue for storing the visited nodes of the graph / tree. Example : Consider the below step-by-step BFS traversal of the tree. Web20 feb. 2024 · The breadth-first search or BFS algorithm is used to search a tree or graph data structure for a node that meets a set of criteria. It begins at the root of the tree or graph and investigates all nodes at the current depth level before moving on to nodes at the next depth level. You can solve many problems in graph theory via the breadth-first ...
