- Solve problem on 79 Project Euler. This is a Graph problem in disguise, so the key is to figure out what is node and what is an edge. In other words, what are the things that have relationships in this problem and what defines their relationships? Once you figure that out, you can use topological sort to solve the problem. Create an account on the site to confirm your answer. You can do this in any language, but a key to solving the problem is finding the indegree of each node. The indegree of a node in a directed graph is the number of edges that have that node as a destination,1 or the number of edges that lead into the node. JUNG has a built in method for graphs to do this. The other thing to keep in mind for JUNG is that you can’t make two edges with the same value. So if you’re using a String to represent edges, you can’t have two edges with the value of "A". please use java and intellijSolve problem on 79 Project Euler.

- Assume you are to write a program to analyze the social connection between students in MTSU. Each student is a node in a undirected graph. An edge is added between two nodes if these two students have close social connections, i.e., in the same club, or in the same department. Which would be a better representation for this graph? Question 45 options: adjacency matrix representation adjacency list representationThe query's nodes are defined by code. The query graph defines a specific collection of nodes and associated properties. For example, this description states that the query network must contain six nodes (1–6), with two square nodes (2 and 6) and two hexagon nodes (1 and 5). The last two nodes (3 and 4) can be of any form.Incidence Table 1 A 1 -1 0 B 0 0 0 C 0 -1 0 0 D 0 0 1 1 E 0 0 0 0 0 -1 -1 For Items 18-22, refer to the incidence table on the previous page 18.

- Exercise # 4: Level of each node in the graph How to determine the level of each node in the given graph? As you know, BFS involves a level-order traversal of a graph. Hence, you can use BFS to determine the level of each node as well. S Level 0 1 Level 1 Level 2 3 4 5 6. Level 3 Exercise # 4a: Write a function nodes_of_level(G, level) that takes a graph and level number as input and returns a list of all the nodes that are on the given level. Example 1: Input Adjacency list representation of graph shown above. level = 1 Output [1, 2] Example 2: Input Adjacency list representation of graph shown above. level = 2 %3D Output [3, 4, 5, 6] 9, 2.Additional Topics: Topological Sort A strict order relation can be represented by a directed acyclic graph (or DAG), which is a directed graph with no cycles. For example, the following directed graph is a DAG: A topological sort of a DAG is an ordering of the vertices that is consistent with the edges of the graph. That is, if there is an edge (u, v) in the graph, then u should appear before v in the topological sort. For example, 1,2,3 and 1,3, 2 are topological sorts of the DAG shown above, but 2,1,3 is not a topological sort because 2 cannot be listed before 1. 7. Given the following DAG G representing UIC's Computer Science courses and prerequisites (note that edges implied by the transitive property are omitted): CS 261 CS 362 CS 141 CS 11 CS 211 Cs 361 CS 401 CS 151 CS 251 CS 342 Cs 301 Answer the following questions: a. Give two different topological sorts of G. b. Is each of the following orderings a topological sort of G? Justify your answer. CS111, CS151, CS301, CS251,…Given a graph data structure: G = (V,E) where, V = {A, B, C, D, E } E = { (A,B), (A,D), (B,D), (B,C), (D,E) } a) Draw the graph G. b) Draw all spanning trees of the graph G, which are also “linear” (each graph node has no more than two neighbors).
- In the context of graph databases, compare and contrast different graph traversal algorithms (e.g., BFS, DFS) and their applications.Write to code describes how to create the links dataset that represents the input graph. In this particular case, the links represent a directed network. The links dataset has only the nodes identification, which means, the from and to variables. The link weights in the transitive closure problem are irrelevant. In other words, it doesn’t matter the cost or the weight of the links, the algorithm searches for the possible paths to connect the nodes within the input graph. If there is a link or a set of links, no matter the weights, that connects node i to node j, that is the matter.Information Cascades It’s election season and two candidates, Candidate A and Candidate B, are in a hotly contested city council race in rainy Eastmoreland. You are a strategic advisor for Candidate A in charge of election forecasting and voter acquisition tactics. Based on careful modeling, you’ve created one possible version of the social graph of voters. Your graph has 10,000 nodes, where nodes are denoted by an integer ID between 0 and 9999. The edge lists of the graphs are provided in the homework bundle. Both graphs are undirected. Given the hyper-partisan political climate of Eastmoreland, most voters have already made up their minds: 40% know they will vote for A, 40% know they will vote for B, and the remaining 20% are undecided. Each voter’s support is determined by the last digit of their node id. If the last digit is 0–3, the node supports A. If the last digit is 4–7, the node supports B. And if the last digit is 8 or 9, the node is undecided. The undecided voters will go…
