Dfs finishing time
WebApr 2, 2010 · DFS time-stamps each vertex when its color is changed. 1. When vertex v is changed from white to gray the time is recorded in d[v]. 2. When vertex v is changed from gray to black the time is recorded in f[v]. The discovery and the finish times are unique integers, where for each vertex the finish time is always after the discovery time. WebQuestion: (5 points) Find a topological sort of the following graph using DFS. You must label each vertex with its DFS finishing time and list the vertices according to the resulting topological sort. (Please conside vertices in increasing alphabetical order. Also visit each vertex's neighbors in increasing alphabetical order.) B A D E

WebPart A: BFS and DFS Practice. Consider the following directed graph: First, perform a BFS on the graph starting with vertex E. If you have to choose between edges at a given step, pick the edge that ends with the vertex that comes first in the alphabet. Question A1: what are the distances assigned by BFS to each vertex? Question A2: which edges ... Web3.1.3 DFS Algorithm The DFS procedure takes as input a graph G, and outputs its predecessor subgraph in the form of a depth-first forest. In addition, it assigns two timestamps to each vertex: discovery and finishing time. The algorithm initializes each vertex to “white” to indicate that they are not discovered yet.
