(a)Find the depth rst tree of G, rooted at b, provided the vertices are ordered alphabeti-cally. Let T = (V;E) is a complete binary tree. d) Bellman–Ford algorithm spanning tree algorithm ? (1 = N = 10000), (1 = M = 100000) M lines follow with three integers i j k on each line representing an edge between node i and j with weight k. The IDs of the nodes are between 1 and n inclusive. Here is an algorithm which compute the 2nd minimum spanning tree in O(n^2) First find out the mimimum spanning tree (T). By continuing, I agree that I am at least 13 years old and have read and agree to the. Start the algorithm at vertex A. In Kruskal's Minimum Spanning Tree Algorithm, we first sort all edges, then consider edges in sorted order, so a higher weight edge cannot come before a lower weight edge. Dijkstra is an algorithm for finding single source shortest paths. 63. Consider a undirected graph G with vertices { A, B, C, D, E}. 6 pts. A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. The edge weights of only those edges which are in the MST are given in the figure shown below. nodes. 5. Its adjacency matrix is shown below. Q. Which of the following is not the algorithm to find the minimum spanning tree of the given graph? The minimum spanning tree ( MST) is of weight 36 and contains the edges: { ( A, C ), ( B, C ), ( B, E ), ( E, F ), ( D, F )}. –Calculators are also permitted but not necessary.

An undirected graph G has n nodes. Question: 1. Use the graph to answer questions #3 - #5. DOUBT ON MINIMAL SPANNING TREE II. Prim’s and Kruskal’s algorithms will always return the same Minimum Spanning tree (MST). Let s and t be two vertices in a undirected graph G + (V, E) having distinct positive edge weights. Consider the edge e having the minimum weight amongst all those edges that have one vertex in X and one vertex in Y The edge e must definitely belong to: The minimum weight edge on any s-t cut is always part of MST. Solve practice problems for Minimum Spanning Tree to test your programming skills. Let the edges have weights: ab = 6, bc - 7, cd = 4, da = 5, ac = 3. Minimum spanning tree is the spanning tree where the cost is minimum among all the spanning trees. Consider a complete graph G with 4 vertices. False 9. View Answer, 6. (c) is false because (b) is true. (6 A new road, of length x km, is built connecting I to J. II is true Let the heavies edge be e. Suppose the minimum spanning tree which contains e. If we add one more edge to the spanning tree we will create a cycle. 1. A minimum spanning tree would be one with the lowest total cost, representing the ..... path for laying the cable. Given a weighted, undirected and connected graph. Weight of the other path is increased by 2*10 and becomes 25 + 20. The task is to find the sum of weights of the edges of the Minimum Spanning Tree. View Answer, 10. Which of the following statements is false? EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. Popular Practice Tests. Which of the following is false in the case of a spanning tree of a graph G? View Answer. CSE332 Summer 2012 Final Exam, August 15, 2012 SOLUTIONS Please do not turn the page until the bell rings. Rules: –The exam is closed-book and limited-note. Stack Overflow Public questions & answers Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers Jobs Programming & related technical career opportunities So the minimum possible weight of ED is 7, minimum possible weight of CD is 16 and minimum possible weight of AB is 10. Which one of the following cannot be the sequence of edges added, in that order, to a minimum spanning tree using Kruskal’s algorithm? Question 2. The graph shown below has 8 edges with distinct integer edge weights. Its adjacency matrix is given by an n × n square matrix whose a) A spanning tree vertices. So, AB should be greater than max(AC, BC) (greater and not equal as edge weights are given to be distinct), as otherwise we could add AB to the minimum spanning tree and removed the greater of AC, BC and we could have got another minimum spanning tree. Question 2 A network can have only one source and one sink. A sample graph with n = 4 is shown below. Solution for PROBLEM 5 Use Prim's algorithm to compute the minimum spanning tree for the weighted graph. c) Graph M has 3 distinct minimum spanning trees, each of cost 2 The weight of a minimum spanning tree of G is 500. The weight of a spanning tree is the sum of all the weights assigned to each edge of the spanning tree. What is the minimum possible weight of a spanning tree T in this graph such that vertex 0 is a leaf node in the tree T? Q. The graph G has ____ spanning trees. The minimum possible sum of weights of all 8 edges of this graph is ______________. On reflection I don't think they can be simple, and multple edges are allowed. Qno1: Answer: I. Let G=(V, E) be a rectangular graph where V = {a, b, c, d} and E = {ab, bc, cd, da, ac}. 0 answers.

Assume the opposite to obtain a contradiction. The edge weights of only those edges which are in the MST are given in the figure shown below. An undirected graph G(V, E) contains n ( n > 2 ) nodes named v1 , v2 ,….vn. d) Removing one edge from the spanning tree will not make the graph disconnected Input: The first line of input contains an integer T denoting the number of testcases. Graph G has no minimum spanning tree (MST), Graph G has multiple distinct MSTs, each of cost n-1, Graph G has multiple spanning trees of different costs. The edge (d-e) cannot be considered before (d-c) in Kruskal's minimum spanning tree algorithm because Kruskal’s algorithm picks the edge with minimum weight from the current set of edges at each step. False 8. Once we have MST of the remaining graph, connect the MST to vertex 0 with the edge with minimum weight (we have two options as there are two 1s in 0th row). Since any minimum spanning tree must contain the unique lowest weighted edge if there is one (i.e. It will take O(n^2) without using heap.
