It involves exhaustive searches of all the nodes by going ahead, if possible, else by backtracking.
WebThe purpose of the algorithm is to mark each vertex as visited while avoiding cycles. The DFS algorithm works as follows: Start by putting any one of the graph's vertices on top of a stack.

WebMar 24, 2024 · To avoid infinite loops, DFS should keep track of the nodes it expanded. That way, it doesn’t explore any node more than once, so it can’t get stuck in a loop. We call that version of DFS a graph-search DFS (GSDFS) since it can handle graphs in general, not just trees. 3. Iterative Deepening DFS has two shortcomings: It may miss the optimal path.
