WebFeb 20, 2024 · Breadth First Search (BFS) algorithm traverses a graph in a breadth-ward motion and uses a queue to remember to get the next vertex to start a search when a dead end occurs in any iteration. BFS is basically a nodebased algorithm which is used to find the shortest path in the graph between two nodes. WebFeb 19, 2024 · Breadth First Search (BFS) is a fundamental graph traversal algorithm. The way it works is, for every node, we scan all of its adjacent nodes, and store them so that we can scan each of them in turn in the next iteration. BFS Levels on a sample graph. Image by author.
