- In a network of N nodes, how many iterations are required for Dijkstra's algorithm to completes its execution. Hint: Section 5.2.1 has the pseudo code for Dijkstra's link state algorithm that finds the shortest path from a source node to every node in the network. Professor Kurose shows the pseudo code in his video. The pseudo code in the text shows an initialization step and then a loop. How many times would the loop be executed for a network of N nodes? O N+1 times ON-1 times ON times O N² timesUsing a teleportation probability of 0.25, setup the matrix calculations for computing the PageRank of the nodes in the web graph. Calculate the PageRank for each node after one iteration. Please show the work to achieve maximum points. B D A C EIn a lecture the professor said that for every minimum spanning tree T of G there is an execution of the algorithm of Kruskal which delivers T as a result. ( Input is G). The algorithm he was supposedly talking about is: Kruskal() Precondition. N = (G, cost) is a connected network with n = |V| node and m = |E| ≥ n − 1 edges.All edges of E are uncolored. postcondition: All edges are colored. The green-colored edges together with V form one MST by N. Grand Step 1: Sort the edges of E in increasing weight: e1 , e2, . . . , em Grand step 2: For t = 0.1, . . . , m − 1 execute: Apply Kruskal's coloring rule to the et+1 edge i dont really understand this statement or how it is done. can someone explain me what he meant?
- Homework due Sep 15, 2022 03:59 +04 Exercise 1 In Exercise 1, we will calculate the chance homophily for an arbitrary characteristic. Homophily is the proportion of edges in the network whose constituent nodes share that characteristic. How much homophily do we expect by chance? If characteristics are distributed completely randomly, the probability that two nodes and y share characteristic a is the probability both nodes have characteristica. which is the marginal probability of a squared. The total probability that nodes x and y share their characteristic is therefore the sum of the square of the marginal probabilities of each characteristic in the network. Instructions • Create a function marginal_prob that takes a dictionary chars with personal IDs as keys and characteristics as values; it should return a dictionary with characteristics as keys and their marginal probability (frequency of occurence of a characteristic divided by the sum of frequencies of each characteristic) as…The size of the optimal linked-list of nodes is unknown. Is there one that obviously takes the largest amount of time?Write the algorithm that finds and returns how many paths in k units of length between any given two nodes (source node, destination node; source and target nodes can also be the same) in a non-directional and unweighted line of N nodes represented as a neighborhood matrix. (Assume that each side in the unweighted diagram is one unit long.) Note: By using the problem reduction method of the Transform and Conquer strategy, you have to make the given problem into another problem. Algorithm howManyPath (M [0..N-1] [0..N-1], source, target, k)// Input: NxN neighborhood matrix, source, target nodes, k value.// Ouput: In the given line, there are how many different paths of k units length between the given source and target node.
- Given N cities represented as vertices V₁, V2, 9 un on an undirected graph (i.e., each edge can be traversed in both directions). The graph is fully-connected where the edge ei, connecting any two vertices vį and vj is the straight-line distance between these two cities. We want to search for the shortest path from v₁ (the source) to vn (the destination). Assume that all edges have different values, and e₁, has the largest value among the edges. That is, the source and destination have the largest straight-line distance. Compare the lists of explored vertices when we run the uniform-cost search and the A* search for this problem. Hint: The straight-line distance is the shortest path between any two cities. If you do not know how to start, try to run the algorithms by hand on some small cases first; but remember to make sure your graphs satisfy the conditions in the question.Daniel and Ria are taking a road trip from Somerville to Vancouver (that’s in Canada). Because it’s a 52-hour drive, Daniel and Ria decide to switch off driving at each rest stop they visit; however, because Ria has a better sense of direction than Daniel, she should be driving both when they depart and when they arrive (to navigate the city streets). Given a route map represented as a weighted undirected graph G = (V, E, w) with positive edge weights, where vertices represent rest stops and edges represent routes between rest stops, devise an efficient algorithm to find a route (if possible) of minimum distance between Somerville and Vancouver such that Daniel and Ria alternate edges and Ria drives the first and last edge. Specify the space and time complexity.Recall that we discussed the "leader-based" deterministic distributed algorithm for 2-colouring a path, that runs in time O(n) on an n node path network. Suppose we now relax the constraint of 2-colouring to mean, it is okay for one of the neighbours of a node to x get the same colour as the mode x, as long as the other neighbour gets a different colour. The end points must get a different colour from their respective unique neighbours. The running time for a best efficiency deterministic distributed algorithm, using unique identifiers for nodes, for this problem would be:
- A weighted graph consists of 5 nodes and the connections are described by: i. ii. iii. iv. Node 1 is connected with nodes 2 and 3 using weights 2 and 6 respectively.Node 2 is connected with nodes 3, 4 and 5 using weights 7, 3 and 4 respectively.Node 3 is connected with nodes 4 and 5 using weights -2 and 2 respectively.Node 4 is connected with node 5 using weight -1. Solve the problem for finding the minimum path to reach each nodes from the first nodeGiven a graph of friends who have different interests, determine which groups of friends have the most interests in common. Then use a little math to determine a value to return. The graph will be represented as a series of nodes numbered consecutively from 1 to friends_nodes. Friendships have evolved based on interests which will be represented as weights in the graph. Any members who share the same interest are said to be connected by that interest. Once the node pairs with the maximum number of shared interests are determined, multiply the friends_nodes of the resulting node pairs and return the maximal product.Let A, B, C, D be the vertices of a square with side length 100. If we want to create a minimum-weight spanning tree to connect these four vertices, clearly this spanning tree would have total weight 300 (e.g. we can connect AB, BC, and CD). But what if we are able to add extra vertices inside the square, and use these additional vertices in constructing our spanning tree? Would the minimum-weight spanning tree have total weight less than 300? And if so, where should these additional vertices be placed to minimize the total weight? Let G be a graph with the vertices A, B, C, D, and possibly one or more additional vertices that can be placed anywhere you want on the (two-dimensional) plane containing the four vertices of the square. Determine the smallest total weight for the minimum-weight spanning tree of G. Round your answer to the nearest integer.
