WebMay 22, 2010 · If we have a directed acyclic graph (DAG) as described in the first section of this page, we can perform a topological sorting to get a topological ordering of the nodes in the graph. A topological ordering is an ordering of the DAG's nodes, such that each node comes before all nodes to which it has outbound edges. WebGiven a graph, we can use the O(V+E) DFS (Depth-First Search) or BFS (Breadth-First Search) algorithm to traverse the graph and explore the features/properties of the graph. Each algorithm has its own characteristics, features, and side-effects that we will explore in this visualization.This visualization is rich with a lot of DFS and BFS variants (all run in …

WebAnswer (1 of 4): Yes, BFS could be used for topological sort. It would take O( E + V ) time. The idea is to start from any vertex which has in-degree of zero, print that vertex and prune the outgoing edges of it and update in-degrees of its neighbors accordingly. Here are the detailed steps which... Web(b) T F The depth of a breadth-ﬁrst search tree on an undirected graph G= (V;E) from an arbitrary vertex v2V is the diameter of the graph G.
