WebUndirected Graphs. We define an undirected graph API and consider the adjacency-matrix and adjacency-lists representations. We introduce two classic algorithms for searching a graph—depth-first search and breadth-first search. We also consider the problem of computing connected components and conclude with related problems and applications. WebAug 5, 2024 · The Depth First Search (DFS) is a graph traversal algorithm.

WebFeb 16, 2024 · 1. Basically, there are two algorithms used for topological sort, described on Wikipedia. Kahn's algorithm works with any graph traversal, including BFS or DFS. Tarjan's algorithm, which is now the most well known, uses a "reverse DFS postorder" traversal of the graph. Postorder means you add a node to the list after visiting its children. WebGiven a directed graph. The task is to do Breadth First Traversal of this graph starting from 0.
