WebCheck out this image:- DFS Traversal Tree. All types of edges appear in this picture. Trace out DFS on this graph (the nodes are explored in numerical order), and see where your intuition fails. Back Egdes: If there is an edge … 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 $${\displaystyle O( E )}$$, with the possibility of duplicate vertices on the stack: See more The computational complexity of DFS was investigated by John Reif. More precisely, given a graph $${\displaystyle G}$$, let $${\displaystyle O=(v_{1},\dots ,v_{n})}$$ be the ordering computed by the standard recursive DFS algorithm. This ordering is called the … 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 … 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 … 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.
