WebAug 5, 2024 · The Depth First Search (DFS) is a graph traversal algorithm. In this algorithm one starting vertex is given, and when an adjacent vertex is found, it moves to that adjacent vertex first and try to traverse in the same manner. It moves through the whole depth, as much as it can go, after that it backtracks to reach previous vertices to find new ... WebMar 13, 2024 · 1. DFS can be used to solve the connectivity problem. You continue to run it on different components until the entire graph is "discovered". Under any case, it does not take longer than V + E. if none of the edges are connected, then you will simply run DFS on every vertice until you discover your graph is disconnected.
