DFS vs BFS — [Notes]. A DFS will only store as much memory

WebDepth-First Search also stores a frontier (or stack in the case of DFS) of nodes to visit next. However, in the case of DFS, this generally grows less quickly. Whenever you visit a node (pop it off of the stack), you generate all of its children and push them on top of the stack. WebThe time complexity of DFS is O (V+E) where V stands for vertices and E stands for edges. DFS requires comparatively less memory to BFS. Some Applications of DFS include: Topological sorting, Finding connected components, Finding articulation points (cut vertices) of the graph, Solving puzzles such as maze and Finding strongly connected components. iremit perth
