In a high school class, there are students of different talents (ex. music, art, debate, sports, etc.). A committee needs to be formed consisting of the maximum number of students such that the committee is diverse – no two students with the same talent are in the committee. Transform this problem to a graph theoretic problem. What are the vertices of the graph? What are the edges of the graph? What do you have to find in the graph?
Among each pair of the CEOs of N companies there is (a) mutual like; (b) mutual dislike; (c) neutral feeling. A trade delegation of the maximum size needs to be formed such that it does not have any pair of members with mutual dislike. Transform this problem to a graph theoretic problem. What are the vertices of the graph? What are the edges of the graph? What do you have to find in the graph?
Chess is a board game, where the board is made up of 64 squares arranged in an 8-by-8 grid. One of the pieces is a rook, which can move from its current square any number of spaces either vertically or horizontally (but not diagonally) in a single turn. Discuss how you could use graphs to show that a rook can get from its current square to any other square on the board in at most two turns. You’re encouraged to utilize relevant graph definitions, problems, and algorithms where appropriate.
The graph G1 has 5 vertices, all of degree 2. How many edges does G1 have? The graph G2 has 8 vertices, all of degree k. Also, G2 has 16 edges. What is k? The graph G3 is a planar graph with 12 vertices and 48 edges. How many regions does G3 have? (Count outside as a region too)
I know that there is an answered question on the question bank, but there are syntax errors the computer caused, so I don't understand it correctly. Prove that the two graphs below are isomorphic. Figure 4: Two undirected graphs. Each graph has 6 vertices. The vertices in the ﬁrst graph are arranged in two rows and 3 columns. From left to right, the vertices in the top row are 1, 2, and 3. From left to right, the vertices in the bottom row are 6, 5, and 4. Undirected edges, line segments, are between the following vertices: 1 and 2; 2 and 3; 1 and 5; 2 and 5; 5 and 3; 2 and 4; 3 and 6; 6 and 5; and 5 and 4. The vertices in the second graph are a through f. Vertices d, a, and c, are vertically inline. Vertices e, f, and b, are horizontally to the right of vertices d, a, and c, respectively. Undirected edges, line segments, are between the following vertices: a and d; a and c; a and e; a and b; d and b; a and f; e and f; c and f; and b and f.
A bank has two sites at which checks are processed. Site1 can process 10,000 checks per day, and site 2 can process6,000 checks per day. The bank processes three types ofchecks: vendor, salary, and personal. The processing costper check depends on the site (see Table 11). Each day,5,000 checks of each type must be processed. Formulate abalanced transportation problem to minimize the daily costof processing checks. Please also provide the graph.
During each 6-hour period of the day, the Bloomington Police Department needs at least the number of policemen shown in the following table. Policemen can be hired to work either 12 consecutive hours or 18 consecutive hours. Policemen are paid $15 per hour for each of the first 12 hours a day they work and are paid $22.5 per hour for each of the next 6 hours they work in a day. Formulate an LP that can be used to minimize the cost of meeting Bloomington’s daily police requirements and solve it via Excel. Time Period Number of required policemen 12:00AM----6:00AM 12 6:00AM----12:00PM 8 12:00PM----6:00PM 6 6:00PM----12:00AM 15
can u solve 5.2 in the exercise . here s the solution of 5.1: Step 1: Understanding the Path Edge Cover Problem In the Path Edge Cover problem, we are given a directed acyclic graph A with two distinguished nodes s (source) and t (sink). The objective is to find the minimum number of directed s-t paths that cover all edges in A. In other words, each edge in the graph must be included in at least one of the chosen paths. arrow_forward Step 2: Transforming Graph A into Graph G To transform A into a graph G suitable for the minimum flow problem, we perform the following steps: Node Splitting: For each node v in A (except s and t), we split v into two nodes vin and vout. Then we add an edge from vin to vout with a lower capacity of 1 and an upper capacity of 1. This enforces that any flow passing through v must be part of exactly one path. Edge Transformation: For each edge (u,v) in A, we create an edge (uout,vin) in G with a lower capacity of 0 and an upper capacity…
For each True/False question enter only Fbecause it will be auto-graded and expects one of these answers only (a) The sum of the degrees of the vertices of a graph can be an odd number. (b) A degree 3 vertex connects to exactly two other vertices. (c) A Hamiltonian cycle must cross every edge of the graph. (d ) A Eulerian trail would begin at an odd vertex and end at another odd vertex . (e) if a graph has n vertices , then there are n ^ 2 spanning trees for this graph .
A major hotel chain is constructing a new resort hotel complex in Greenbranch Springs, WestVirginia. The resort is in a heavily wooded area, and the developers want to preserve as much ofthe natural beauty as possible. To do so, the developers want to connect all the various facilitiesin the complex with a combination walking–riding path that will minimize the amount of pathwaythat will have to be cut through the woods. The following network shows possible connectingpaths and corresponding distances (in yards) between the facilities: Determine the path that will connect all the facilities with the minimum amount of constructionand indicate the total length of the pathway.
Socaccio Pistachio, Inc. makes two types of pistachio nuts: Dazzling Red and Organic. Pistachio nuts require food color and salt, and the following table shows the amount of food color and salt required fo a 1-kilogram batch of pistachios as well as the total amount of these ingridients available each day: Use a graph to show the possible numbers of batches of each type of pistachio Socaccio can produce each day. Dazzling Red Organic Total Available Food color(grams) 2 1 20 Salt(grams) 10 20 220
