WebJun 21, 2024 · C++ DFS for a Graph Article Creation Date : 21-Jun-2024 11:10:48 AM Depth First Search for a Graph Depth First Search (DFS) The DFS algorithm is a recursive algorithm that uses the idea of backtracking. It involves exhaustive searches of all the nodes by going ahead, if possible, else by backtracking. WebDepth First Search (DFS) algorithm traverses a graph in a depthward motion and uses a stack to remember to get the next vertex to start a search, when a dead end occurs in any iteration. As in the example given above, DFS algorithm traverses from S to A to D to G to E to B first, then to F and lastly to C. It employs the following rules.
