WebNov 20, 2024 · Depth-first search (DFS) lives an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as one root in the case of a graph) and explores than far as workable along each branch before backtracking.

WebAug 23, 2024 · 19. 3.1.1. Depth-First Search¶. Our first method for organized graph traversal is called depth-first search (DFS). Whenever a vertex \(v\) is visited during the search, DFS will recursively visit all of \(v\) ‘s unvisited neighbors. Equivalently, DFS will add all edges leading out of \(v\) to a stack. The next vertex to be visited is determined by … WebJan 9, 2024 · A Computer Science portal for geeks.
