Depth First Search Algorithm: A graph search algorithm

WebDepth-First Search - Theory. Depth-First Search (DFS) is an algorithm used to traverse or locate a target node in a graph or tree data structure. It priorities depth and searches along one branch, as far as it can go - until the end of that branch. Once there, it backtracks to the first possible divergence from that branch, and searches until ... WebExample 3: Depth-first search of the same digraph.

The graph has a cycle if and only if there exists a back edge. Now, the representation of undirected graphs chosen by Skiena is to store each undirected edge as two directed arcs, one in each direction.

"WebDepth-first search (DFS) algorithm is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking. DFS is one of the most useful graph search algorithms. Algorithm " - Notes about depth first graph search
