Compute pre and post values for the vertices of this graph. The pre and post timestamps for the selected vertices are: vertex B: pre of B is 1 post of Bis 12 vertex C: pre of Cis 6 ; post of Cis 7 vertex G: pre of G is ; post of G is

3.4. Run the strongly connected components algorithm on the following directed graphs G. When doing DFS on GR: whenever there is a choice of vertices to explore, always pick the one that is alphabetically first. S. Dasgupta, C.H. Papadimitriou, and UV. Vazirani 107 In each case answer the following questions. (a) In what order are the strongly connected components (SCCs) found? (b) Which are source SCCs and which are sink SCCs?...

Execute DFS on the graph below, starting in node a. Whenever you have a choice which vertex to visit next, choose the next vertex in the adjacency list of the vertex (e.g., when you have reached node e, you must first try to visit node f, then g, and then . Indicate the outcome of the algorithm by labeling the edges of the graph either as T (tree edge) F (forward edge), B (back edge), or C (cross edge). Label...

Help with Q3 please!
3 (9 pts) For the graph G (VE) in question 2 (above), construct the adjacency lists for G (using alphabetical ordering) and the corresponding reverse graph GR Adjacency list for G (alphabetical ordering): Adjacency list for G. V = {A, B, C, D, G, H, S) V - {A, B, C, D, G, H, S) E A = { EB = EC) - E[D] = {C,G) E[G] - [ ECH - E[S { EA = {...

Write a C++ program called ts.cpp that implements the topological sorting algorithm based on the DFS algorithm. Your program should read an input file name and determine if the input graph is a DAG (= directed acyclic graph) or not. If the graph is not a DAG, your program has to stop without further processing. However, if it’s a DAG, your program should display the starting node(s), popping-off order, and topologically sorted list. In the problem, you can assume that...

Question 1.) Given a directed negative weights Graph what is the most efficient algorithm to detect a cycle. What is the most efficient method to detect a cycle? Question 2.)Let A= student id last digit % 4 and add 1. For example mine student id is 7. So 7%4=3 and add 1 -->A=4 Run DFS starting at node a, and breaking ties alphabetically(in this case numerically as nodes have numbers where 1 goes before 2). Please label just back edges....

(c) Simulate breadth first search on the graph shown in Fig
HW2Q1c. You can assume that the starting vertex is 1, and the
neighbors of a vertex are examined in increasing numerical order
(i.e. if there is a choice between two or more neighbors, we pick
the smaller one). You have to show: both the order in which the
vertices are visited and the breadth first search tree. No
explanations necessary.
(d) On the same graph, i.e. the graph in...
