Santa 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 - ).
The graph below represents the possible routes that can be built in a city to improve mobility between neighborhoods, the label on the sides is the number of houses that must be knocked down to build the route. What is the minimum number of houses that must be demolished to build the routes between neighborhood A and the neighborhood L?

- Imagine a project, and then map it both with and without architecture. what effect it will have on the finished itemarrow_forwardAs a project your team is given the task of designing a space station consisting of four different habitats. Each habitat is an enclosed sphere containing all necessary life support and laboratory facilities. The masses of these habitats are 1.0 x 106 kg, 2.0 x 106 kg, 3.0 x 106 kg, and 4.0 x 106 kg. The entire station must spin so that the inhabitants will experience an artificial gravity. Your team has decided to arrange the habitats at corners of a square with 1.0 km sides. The axis of rotation will be perpendicular to the plane of the square and through the center of mass. To help decide if this plan is practical, you calculate how much energy would be necessary to set the space station spinning at 1.0 revolution per minute. In your team's design, the size of each habitat is small compared to the size of the space between the habitats and the structure that holds the habitats together is much less massive than any single habitat. how much energy would be necessary to set the space…arrow_forwardIn a nutshell, this is what we mean when we talk about cooperative learning.arrow_forward
- Consider the following task of building a zoo for Drexel! You’ve gathered m donors to fund the creation ofyour new park, and you’ve picked the location, so now you just need to choose the inhabitants. Ideally you’dget every animal imaginable, except you just don’t have space. As it is, you have room to comfortably fitk animals. Since you’d like to ensure that your funding doesn’t dry up, you figure your donors should getto make requests about which animals will be kept. After sending out a few emails, you collect from eachdonor i a list of animals Ai which donor i would like to have at the zoo. As you suspected, the total numberof different animals appearing on the m lists exceeds k, so you won’t be able to satisfy all of their requests.You decide the fairest thing to do is to ensure that at least 1 animal from each Aiis chosen.Given all these lists, we want to know whether we can select a set H of at most k animals to put in thezoo such that each donor i will be able to see at least…arrow_forwardHow can the many choices available be used to lower the amount of extra costs that NPT causes?arrow_forwardSuppose you have this problem scenario: Ali was asked to develop an e- learning website.

- Each proposed change to the framework should include potential roadblocks and their solutions. This has to be done before we can go on to brainstorming ways to fix the problems we've found. The idea of using cloud computing to fix these issues is appealing, but is it feasible? Compared to what, exactly, is this more crucial?arrow_forwardQuestion 2: Suppose you have the following scenario: People who use the Palm Tree System are either farmers or experts. They both have name and phone number. The farmer has an address and has the ability to search and buy a product, reserve an appointment and add comments. An expert has a number of years of experience and can answer questions and post advices. An Expert can communicate with many farmers while a farmer can communicated by only one expert. By using Star UML tool, draw a Class diagram for this scenario.arrow_forwardA library wants to build a simple online recommendation system for a summer reading programme. The system involves people reading and recommending books and authors. • Readers (people) have a screen name as well as a real name and contact information, including an unknown number of phone numbers they can be contacted at. • Books have a title, ISBN, genre and reading level. • An author has a name and nationality. They can write zero or more books. • Assume that Books are written by only one author. • The database records what books a reader has read. • Readers can “like” books. • Readers can “like” authors independent of the books the author has written. Create a hand-drawn, conceptual entity relationship diagram (like the last lab, except that you’re including attributes) describing this circumstance for a database designer.arrow_forward

Assume that the temperature of any single cell is equal to the average of the temperatures of the four cells which share a side with it. Create a 10 by 10 cell finite element model with the temperature of the top edge (all 10 cells) is held to 20 degrees C, and the temperature along the right side is also held to 20 degrees. Make the lower left corner "hot" -- you can pick a value similar to a that of a soldering iron (look up temperatures of soldering iron tips). You can then add values long the bottom going from high down to 20 degrees, decreasing from left to right -- choose any starting rate you like. You can do the same for the left side, going from 20 degrees at the top and going up to the high temperature you have assigned in the lower left corner.
