Dfs of a directed graph

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 . WebMay 23, 2015 · You can use Dijkstra's algorithm instead of BFS to find the shortest path on a weighted graph. Functionally, the algorithm is very similar to BFS, and can be written in a similar way to BFS. The only thing that changes is the order in which you consider the nodes. For example, in the above graph, starting at A, a BFS will process A --> B, then ...

Detect Cycle in Directed Graph - Scaler Topics

WebApproach 1: Using Depth First Search (DFS) To detect the cycle in a directed graph, we will be using the DFS technique. We know that the DFS of the directed graph generates a DFS tree (s), which is nothing but the representation of vertices and edges of the provided graph. When we perform DFS on a disconnected graph, multiple such trees hence ... WebMay 27, 2024 · Find a cycle in undirected graphs.
