A blue node An edge connecting a blue node and a green node. [Image source: https://en.wikipedia.org/wiki/Graph_coloring] A simple graph can be expressed by the following two predicates. Given the predicates below: Edge(x, y): x is connected to y Color(x, z): x has color z and the following domains: domain of x and y: {all nodes in a graph}, domain of z: {RED, GREEN, BLUE, YELLOW}, translate the following statements into English. a) Vx 3y Edge(x, y) b) Vz 3x Color(x, z) c) VxVvVz (Edge(x, v)A Color(x. z) → -Color(y, z))

People is represented in the Graph by Nodes or Vertices (the vertex should consist of name of the person) Relationships is represented in the Graph by edges or arcs The project should have at least two class with following methods : addNode add vertices to graphs(New person in the Graph Net ) removeNode removes vertices to graphs(remove person from the graph Net) addEdge adds connections or paths between vertices in graphs(make new relationship between two persons in the graph ) removeEdge removes connection or paths between vertices in graphs (remove the relationship between two persons in the graph ) contains check if a graph contains a certain value hasEdge checks if a connection or path exists between any two vertices in a graph The output has to display a menu of choices. Then the user can select which operation want to perform. Also, you can use the method System.exit(0); to exit the program. The menu of choices will be: Add person into the social…
i want code in c language A food based company wants their users to rate their newly launched food items, items are Burger, Broast, Rice, Roll, Handi, Platter, Kebabs, Sandwich, Shake, Kheer. Scoring can be done from 1 to 10, best towards worst respectively. Design a solution that saves the food items and then let users rate these food items along with their comments. A bar graph based on rating should also be printed Note: (Structures must be used to save the data) A sample run of the application is shown as follows: Enter score for Burger (1-10) 8 Enter reason for liking or disliking Fresh and juicy Output of your program should be as follows Item Rating Reason Histogram Burger. 8 Fresh and juicy ******** Broast 4 Taste was not good **** . . . . . . . .

Java program help Simulate a slot machine. The customer will add a fixed amount of money to the machine and play the slots. There should be 4 images for the game: "Apple", "Orange", "Banana", and "Cherry". If three of the images match, the customer wins $2 and is added to their balance. If all four match, the customer wins $10 and that is added to their balance. If less then four match there is no prize money, and the customer is charged $1 for the try. The customer can quit after each try, and the program will print out the customer's cash balance. Coding Details: Use an array of strings to store the 4 strings listed above. Use a do-while loop for the program. The program starts once the user enters how much money they have. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for the program is shown below: Determine the fruits to display (step 3 below) and print them Determine if there…
AVA code OVERVI EW This is a review exercise, so the primary goal of the exercise is to get your mind working and in the correct space.In this activity you will create a imaginary grid of locations that goes from −?≤?≤?, −?≤?≤?, with the coordinate (0,0) being "home". On this grid you will keep track of various animal objects as they move around the grid. Make sure that all animals stay within that grid at all timesincluding when they are created. Zwill be the map size and will control the highest number allowed on themap before wraping around. Using Java, create the following classes and primary program that uses the classes that you developed. INS T RUCT IONS Create the following classes. A N I MA L C LA SS Create an Animal class. Each animal has a name, an x and y integer coordinate. The Animal class should have at minimum the following methodsbelowbut you may want to add more if necessary: Also note, everyanimal will need to have to have “z”passed to it so that it knows how big the…
In a graph, two vertices are connected if there is a path between them. If all vertices are connected, we say the graph is connected. Given the Graph ADT below: class Graph { public: void addEdge (int vl, int v2); void delEdge (int vl, int v2); bool hasEdge (int v1, int v2) const; VList adj (int v) const; int v() const; int e() const; } ; Fill in the function isConnected that tells whether graph g is connected or not. Note that you can only use the above methods for g. You may assume vertex ID starts from 0 and define other helper functions if necessary. bool isConnected (const Graph &g) { // Copy this function in the answer and add code below this line. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
Python Graph Algorithms: Minimum Spanning Trees Suppose you are an engineer working on designing a road network for a new town. The town has many residential areas and commercial centers that need to be connected efficiently. You decided to represent the town as a connected, undirected graph where each vertex represents a location, and each edge represents a road connecting two locations. The weight of each edge represents the distance between the two locations. To ensure the road network is efficient, you need to find the minimum spanning tree of the graph. However, due to budget constraints, you can only construct roads with a maximum distance limit. You need to determine for how many pairs of locations, the minimum spanning tree of the graph remains the same when the maximum distance limit of a road is increased by 2 units. To solve this, you write a program that takes as input the number of locations, the number of roads, and the weight of each road. Your program will also receive…

Simulation parameters: • Define a step size h. Try something small like 0.001 seconds. • Define a length for the simulation-perhaps 10 seconds for now, but feel free to adjust it as you see fit. • Create a list of times that begins at 0 and goes up to the simulation length in steps of h. The actual simulation only cares about the step size, so we won't use this in the simulation but we'll use it for plotting at the end. • Calculate the length of the list created in the previous step and assign it to a variable n. Data arrays: • Create a list r of length n that is all zeros (np.zeros could come in handy here). • Create a list s of length n that is all zeros. Initial conditions: • Set the first entry of r to be some initial height of your choosing. • Set the first entry of s to be some initial velocity of your choosing. First-order equations: • We need to define a function that calculates the derivative of r. Since Eq. 2.14 says that r' s, this is fairlv simply. We iust have to return c…
