Suppose that Donald owns a building that is worth $606 million to him. There is another person in the city, Bernie, who values the building at $1,312 million (we know this to be objectively true). Would it be efficient for the mayor of the city to seize the Donald's property and transfer it to Bernie? Explain.

- Consider the following scenario: A teacher interviews a student, and during the interview the teacher always grades the student. This scenario can be modeled with two use cases -- "Conduct Interview" and "Grade Student". What is the relationship between these two use cases? a) Conduct Interview extends Grade Student b) Grade Student extends Conduct Interview c) Conduct Interview includes Grade Student d) Grade Student includes Conduct Interview1. Consider the following simplified version of Google’s advertising auction. Assume that there are three bidders for a certain keyword and two positions for sponsored clicks. The bidders’ respective values per click are £60, £30 and £20. The valuations are common knowledge among bidders. The click-through rate for the top position is 400 clicks per hour, and for the second position it is x clicks per hour. a) In the generalised second-price (GSP) auction, for which x is it optimal for bidders to bid their respective value per click if all other bidders also bid their values per click? What is the revenue of the auction? How does it compare to the revenue in the Vickrey-Clarke-Groves (VCG) mechanism? b) Suppose that x = 200, and suppose that bidder 1 only bids a fraction α (α ≤ 1) of her value per click (and the other two bidders bid their full value per click). For which α is this an equilibrium in the generalised second-price auction? c) Suppose that x = 200, and…Question 3: Consider a single elimination tournament of 16 football teams, laid out as in the diagram below. Once a team loses it is out of the tournament. Every team must play until it is eliminated. The starting positions for each team are fixed. A matchup (X,Y) represents a game between teams X and Y. A round is the set of all the matchups at a given stage of the tournament (the matchups above the round title in the diagram). Thus round 3 in the diagram below is the set {(D, E), (I,O)} of matchups. An outcome is the union of all the matchups along with the winner. (Essentially two outcomes are different if the winners of the games produce a different letter in at least one place in the diagram below.) A A B C D E F G H D E G D E Round 1 Round 2 Round 3 D WINNER Round 4 O L N -J -K Round 3 Round 2 Round 11 a) How many unique outcomes are there in this tournament? b) How many unique outcomes are there where A wins the entire tournament? c) How many unique outcomes are there where D…
- QUESTION THREE A. Consider the thirsty person problem given below: To drink, a thirsty person must have three things; water, ice and a glass. There are three thirsty people, each having a different one (and only one) of the three required items. A fourth person, a server has unlimited supply of all three items. If nobody is drinking, the server places two of the three items (chosen at random) onto table. Thirsty person who can make a drink from those two items will pick them up and drink a glass of ice water. When done, thirsty person will notify the server and the process will repeat. Write a process that will control the thirsty person and the server using semaphores. (B) (i)What is a critical section in code? (ii) Explain the three properties that any solution to the Critical Section Problem should guarantee. (C) Explain the role the Operating System plays in Garbage-In-Garbage-Out (GIGO).Suppose you've just inherited $10,000 from a relative. You're trying to decide whether to put the $10,000 in a non-interest-bearing account so that you can use it whenever you want (that is, hold it as money) or to use it to buy a U.S. Treasury bond. The opportunity cost of holding the inheritance as money depends on the interest rate on the bond. For each of the interest rates in the following table, compute the opportunity cost of holding the $10,000 as money.Banks lend money to each other. In tough economic times, if a bank goes bankrupt, it may not be able to pay back the loan. A bank’s total assets are its current balance plus its loans to other banks. The diagram in Figure 11.9 shows five banks. The banks’ current balances are 25, 125, 175, 75, and 181 million dollars, respectively. The directed edge from node 1 to node 2 indicates that bank 1 lends 40 million dollars to bank 2. If a bank’s total assets are under a certain limit, the bank is unsafe. The money it borrowed cannot be returned to the lender, and the lender cannot count the loan in its total assets. Consequently, the lender may also be unsafe if its total assets are under the limit. Write a program to find all unsafe banks. Your program should read the input as follows. It first reads two integers n and limit, where n indicates the number of banks and limit is the minimum total assets for keeping a bank safe. It then reads n lines that describe the information for n banks…
- You, Alice and Bob manage "Robo-Pizzeria" a company that uses drones to deliver pizza. Here are some important features of your business model: • Drones can fly directly to a location so the time it takes to travel to a location is proportional to the distance between the two locations. • Delivery locations are given as points in a 2-dimensional plane. The Robo-Pizzeria is located at the origin (0,0). The first problem you are trying to solve is planning the route for your drone to follow while delivering pizzas to n locations. The route must leave from the Robo-Pizzeria, visit all locations, and return while travelling the minimum total distance. a) Show how you can turn these 4 delivery locations into a complete weighted graph with 5 nodes (including the Robo-Pizzeria at the origin) by stating the adjacency matrix for the graph. {(1, 1), (-2,-1), (2, 1), (-3,5)} (Since the graph is undirected you only need to state the upper triangle of the matrix.) b) Now describe the procedure you…QUESTION 15 Al Watan supermarket has hire-purchases scheme for locals and expats.

Students are allowed to enrol in a maximum of 5 units in any given seme ster. They can only be enrolled into a single course at any given point in time. However, over a student's lifetime, they may undertake a number of different courses. Each unit has a set fee that is set at the start of the semester. This fee is to be paid up-front in full by the students once enrolled. Some units have pre-requisite unit requirements. Some units have co-requisite unit requirements. To be enrolled in some courses, you must have completed a certain course (e.g. to enrol into a Postgraduate course, you must have an Undergraduate degree)." Noun (bold)/verb (underline) analysis on the case study is marked for you to identify candidate classes, attributes, operations. Now, draw the domain model for the above case study.

The husband would prefer to go to the football game. The wife would rather go to the opera. Both would prefer to go to the same place rather than different ones. • Suppose they choose to go to the same activity, the one prefers such activity will receive utility of 3 and the other will receive utility of 1. • If they miss each other, they will not receive any utility. If they cannot communicate, where should they go? 1. Write down the payoff matrix of this game. 2. What is the stable optimal strategy for the couple'? Hint: Stable strategy can be drawn from the definition of Nash equilibrium. This is not necessarily a zero-sum game, so you may NOT find the optimal strategy by solving LP.Problem 5: Determine which rule of inference is used in each of the following arguments. 1.
