This Search algorithm combines the benefits of Breadth-first search's fast search and depth-first search's memory efficiency. WebMar 22, 2024 · Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.

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. WebJan 27, 2024 · Similarly, in terms of space complexity, DFS is O(h) and BFS is O(w). For DFS, ‘h’ stands for height since how much space the function will take depends on how many nodes deep the tree is.

DFS and BFS are two graph … The time and space analysis of DFS differs according to its application area. In theoretical computer science, DFS is typically used to traverse an entire graph, and takes time , where is the number of vertices and the number of edges. This is linear in the size of the graph. In these applications it also uses space in the worst case to store the stack of vertices on the current search path as well as the set of already-visited vertices.
