WebBFS and DFS work on both directed and undirected graphs, as shown in the figures above. If the underlying graph is disconnected, BFS and DFS can only traverse the connected component that the given starting node belongs to. BFS cannot be used to find shortest paths on weighted graphs. See Dijkstra’s algorithm for that!

WebFinding the shortest path: In an unweighted graph, the shortest path between two nodes is the path with the least number of edges. BFS can be used to find the shortest path between a source node and all the remaining nodes in an unweighted graph. Finding the minimum spanning tree: After some modifications, this algorithm can be used to find the ... WebIn BFS, we initially set the distance and predecessor of each vertex to the special value ( null ). We start the search at the source and assign it a distance of 0. Then we visit all the neighbors of the source and give each neighbor a distance of 1 and set its predecessor to be the source. Then we visit all the neighbors of the vertices whose ...
