WebJun 5, 2024 · As defined in our first article, depth first search is a tree-based graph traversal algorithm that is used to search a graph. Unlike BFS, a DFS algorithm traverses a tree or graph from the parent vertex down to its children and grandchildren vertices in a single path until it reaches a dead end. WebA depth-first tree is always different from a breadth-first tree rooted at the same vertex for the same graph G. a. True This problem has been solved! You'll get a detailed solution …

WebJul 19, 2013 · When the depth-first search has backtracked all the way back to the original source vertex, s, it has built a DFS tree of all vertices reachable from that source. If there still undiscovered vertices in the graph, then it selects one of them as the source for another DFS tree. The result is a forest of DFS-trees.
