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. Extra memory, usually a stack, is … See more 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 $${\displaystyle O( V + E )}$$, … See more Input: Output: A recursive implementation of DFS: A non-recursive implementation of DFS with worst-case space complexity These two … See more Algorithms that use depth-first search as a building block include: • Finding connected components. • Topological sorting. • Finding 2-(edge or vertex)-connected components. See more For the following graph: a depth-first search starting at the node A, assuming that the left edges in the shown graph are chosen before right edges, and assuming the … See more The result of a depth-first search of a graph can be conveniently described in terms of a spanning tree of the vertices reached during the search. Based on this spanning tree, the edges of the original graph can be divided into three classes: forward edges, … See more The computational complexity of DFS was investigated by John Reif.

How it works is like so: Starting off with a node, we mark it as visited, then for each of its neighbors that is not visited, we call depth first search on them. A recursive implementation of depth-first search. We can also extend the algorithm to ...
WebDepth-first search (DFS) algorithm is an algorithm for traversing or searching tree or graph data structures.
