WebJun 16, 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 tries to traverse in the same manner.

WebJun 3, 2014 · The complexity of DFS is O(n + m) (for both directed and undirected graph) in this case. Proof First consider using adjacency list to represent the graph, where the list for vertex v consists of pointers to the adjacent vertices . WebNov 18, 2024 · This is a Depth First Search (DFS) based algorithm to find all the articulation points in a graph. Given a graph, the algorithm first constructs a DFS tree. Initially, the algorithm chooses any random vertex to start the algorithm and marks its status as visited. The next step is to calculate the depth of the selected vertex.
