Depth first search on undirected graph

WebMar 14, 2024 · Depth-first search (DFS) is a technique that is used to traverse a tree or a graph. DFS technique starts with a root node and then traverses the adjacent nodes of the root node by going deeper into the graph. In the DFS technique, the nodes are traversed depth-wise until there are no more children to explore. WebLet G be an undirected graph and T be a spanning tree of G. In this paper, an efficient parallel algorithm is proposed for determining whether T is an unordered depth-first search tree of G. The proposed algorithm runs in O(m/p+log m) time using p processors on the EREW PRAM, where m is the number of edges contained in G. It is cost-optimal and …

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. forensic economics consultingWebAug 18, 2024 · Depth First Search begins by looking at the root node (an arbitrary node) of a graph. If we are performing a traversal of the entire graph, it visits the first child of a root node, then, in turn, looks at the first child of this node and continues along this branch until it reaches a leaf node. did trinity the tuck dieWebMar 26, 2024 · DFS Algorithm. Step 1: Insert the root node or starting node of a tree or a graph in the stack. Step 2: Pop the top item from the stack and add it to the visited list. Step 3: Find all the adjacent nodes of the node marked visited and add the ones that are not yet visited, to the stack. Step 4: Repeat steps 2 and 3 until the stack is empty. forensic economics incWebTo be short, performing a DFS or BFS on the graph will produce a spanning tree, but neither of those algorithms takes edge weights into account.
