Imagine you are an avid movie goer and you prepared a list of n movies you are considering watching. As a thorough researcher, you prepared a list of k friends, whose movie advice you trust. For each movie, you are debating whether to either see it or speak to all of your friends and hear their recommendations.
A more efficient approach is to choose between watching the movie and speaking with at least one trusted movie recommender friend. This approach will take a total of t hours. Prove that the problem is NP-hard.
Following the success of her basic taxi service and the fact that a number of customers are using the service regularly, Allo taxi has decided to reward regular customers by allowing them to pay their bills on a monthly basis rather than for each individual journey. This means that a series of discounted rates can be offered to customers who use the service on a regular basis. The customer will pay fares based on the frequency they use the service (the number of journeys made in a month) and the number of miles traveled in the month. The Basic Charge (based on the total number of miles) is calculated according to the table below:
Basic charges per mile ($):
Up to 5 journeys
Up to 10 journeys
More than 10 journeys
Up to 100 miles

Dollar General Corporation operates deep-discount stores offering housewares, cleaning supplies, clothing, health and beauty aids, and packaged food, with most items selling for $1. Its business model calls for keeping costs as low as possible. The company has no automated method for keeping track of inventory at each store. Managers know approximately how many cases of a particular product the store is supposed to receive when a delivery truck arrives, but the stores lack technology for scanning the cases or verifying the item count inside the cases. Merchandise losses from theft or other mishaps have been rising and now represent over 3 percent of total sales.

Chris Martin loved the crowd which is why he gave Krushi and Mansi an endless number of Tshirts to give to his fans. They both jumped into the crowd. Chris Martin points to N number of followers one at a time, first at Krushi and then at Mansi. Imagine endless fans arranged with a 2D infinte grid, with each follower standing at each step in an orderly fashion. Chris gives them directions in the form of an S unit and they follow blindly. As a result, few fans appear with more than one T-shirt. Krushi and Mansi start at the same place (bring two T-shirts to the same starting fan), and take turns based on orders from Chris, who gives them orders as follows: U - Move up the stairs D - Go Down one step L- Go Left one step R - Go Right one step Given the S-letter unit of the instructions given to Chris.

- You are interested in looking at how competition affects gas prices, where you think that if a gas station has more competitors nearby, it will tend to have lower prices. To test this, you decide to use a natural experiment in which a chain of gas stations ("Thrifty") suddenly closed. This closure occurred between June and October of 2012, and meant that gas stations that were previous close to a Thrifty station experienced less competition than before. On the other hand, those stations that were not close to a Thrifty station did not experience any change in competition. You decide to use a differences in differences design, in which gas stations located near a Thrifty station at the start of 2012 are the treatment group and those that were not located near a Thrifty at the start of 2012 are the control group. You look at how prices change before and after the exit of Thrifty. This is plotted in the below graph, where the solid line represents the average price of stations that were…arrow_forwardDenial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. The annual loss expectancy (ALE) without controls is $ A . The annual loss expectancy (ALE) with controls is $arrow_forwardDenial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? Calculate the prior and post ALE and do a cost-benefit analysis to answer the question. In your answer make sure that you indicate what ARO, SLE and ALE are with and without controls. State clearly whether the company should implement the controls and explain why.arrow_forward

What is the minimum number of houses that must be demolished to build the routes between neighborhood A and the neighborhood L?arrow_forwardMaking Elevators Go Faster!This story has been reported in numerous places and has almost become a classic example to explain the need for problem identification. Ackoff (as cited in Larson , 1987) described the problem of managing complaints about slow elevators in a tall hotel tower.After trying many solutions for reducing the complaint: staggering elevators to go to different floors, adding operators, and so on, the management determined that the real problem was not about the actual waiting time but rather the perceived waiting time. So the solution was to install full-length mirrors on elevator doors on each floor. As Hesse and Woolsey (1975) put it, "the women would look at themselves in the mirrors and make adjustments, while the men would look at the women, and before they knew it, the elevator was there ." By reducing the perceived waiting time, the problem went away. Baker and Cameron 0996) give several other examples of distractions, including lighting,…arrow_forwardSanta is worried about his employee relations, since christmas preparations have led to a lot of overtime. To make sure all the elves are happy, he wants to recruit some of them as complaint officers, with weekly meetings to report any complaints or worries to him. His worker elves W are pretty busy already, so Santa wants to task no more than k elves with this additional workload. Still, Santa wants to make sure that for as many elves e e W as possible, at least one of his friends (whose identities he knows) is a complaint officer. 1. Give an intuitive greedy algorithm that outputs k elves that will serve as compliant officers. 2. Prove that for large numbers of k the algorithm approximates a solution with ratio no more than (1 - ).arrow_forward
- Read carefully the following case:Imagine that you work as an internal auditor for a company that owns several pharmacies throughout the city. Based on your audit plan, the first cycle to audit will be revenue. The first thing you do is document the processes related to receiving and processing the various sources of income. On your initial visit, you were able to observe the following:Once customers have the items to purchase, they head to the register, where a clerk processes the sale. The pharmacy has three cash registers, but does not have an employee who specifically works as a cashier at each one. This provides flexibility in the operation because, of the three employees that the business has, one can collect at any of the cashiers when available. By not having to leave a single person as a cashier, the cashier can focus on providing more direct customer service, refilling merchandise on the shelves, and even assisting in receiving or dispatching merchandise from the store.At the…arrow_forwardThere are companies or other workplaces that allow trainees like Work Immersion students to just finish the work for the day and they can go home. That scenario happens to you, so you can go home already as per instruction. But you see other trainees like you are still working?arrow_forwardA company has various rules for how payments to suppliers are to be authorized.Some payments are in response to an approved purchase order. For approved purchase orders under $5,000, the accountingclerk can immediately issue a check againstthat purchase order and sign the check. Forapproved purchase orders between $5,000and $10,000, the accounting clerk can immediately issue a check but must additionallyobtain a second signature. Payments for approved purchase orders over $10,000 alwaysrequire the approval of the accounting manager to issue the check as well as the signature of two accounting clerks. Payments thatare not covered by a purchase order that areunder $5,000 must be approved by the accounting manager and a departmental manager who will absorb the cost of the paymentinto that department’s budget. Such checkscan be signed by a single accounting clerk.Payments that are not covered by a purchaseorder that are between $5,000 and $10,000must be approved by the accounting…arrow_forward
