Difference between BFS and DFS
Illustrates the difference between BFS and DFS?
Expert
BFS: It can be thought of as Dijkstra's algorithm for shortest paths, although along with every edge containing similar length. However this is a large number simpler and doesn't require any data structures. We only maintain a tree as the breadth first search tree, this list of nodes to be added to the tree, and markings (i.e. Boolean variables) upon the vertices to signify whether they are within the tree or list.
Depth first search is other way of traversing graphs that is closely associated to preorder traversal of a tree. Recall, which preorder traversal only visits each node before its children. This is most simple to program like a recursive routine:
