WebThe two most common graph traversal algorithms are breadth-first search (BFS) and depth-first search (DFS). The BFS pseudo-code looks like this: ... Time and space complexity. For both BFS and DFS, there are at most V executions of the while loop, as a node can go on the stack or queue at most once, and the body of the loop on successors … WebTime complexity. The time complexity of BFS is O(V + E). V=vertices E= edges. Applications of BFS. BFS is in fact used in a lot of places: 1.BFS is very versatile, we can find the shortest path and longest path in an undirected and unweighted graph using BFS only. Well in case of shortest path we just do a small modification and store the node ...

Overview In Computer Science, … WebDepth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes …
