1 The Traveling Salesman Problem Tsp Is A Famous Problem For Which There Is No Known 2835377

/in /by

1. The Traveling Salesman problem (TSP) is a famous problem for which there is no known,

tractable solution (though efficient, approximate solutions exist). Given a list of cities and the

distances in between, the task is to find the shortest possible tour (a closed walk in which all

edges are distinct) that visits each city exactly once.

Consider the following algorithm for solving the TSP:

n = number of cities

m = n x n matrix of distances between cities

min = (infinity)

for all possible tours, do:

find the length of the tour

if length

min = length

store tour

a) What is the worst-case (big-O) complexity of this algorithm in terms of n (number of

cities)? You may assume that matrix lookup is O(1), and that the body of the ifstatement

is also O(1). You need not count the if-statement or the for-loop conditional

(i.e., testing to see when the for-loop is done), or any of the initializations at the start of

the algorithm. Clearly show the justification for your answer.

b) Given your complexity analysis, assume that the time required for the algorithm to run

when n = 10 is 1 second. Calculate the time required for n = 20 and show your work.

2. Suppose an algorithm solves a problem of size x in at most the number of steps listed in each

question below. Calculate the asymptotic time complexity (big-T or big-theta) for each example

below. Show your work, including values for c and x0along the way.

a) T(x) = 1

b) T(x) = 5x – 2

c) T(x) =3x^3+ 2 + x2

d) T(x) = log (x * 2x!)

1 The Speedway Clinical Laboratory Is A Scientific Blood Testing Facility That Recei 2818849

/in /by

1. The Speedway Clinical Laboratory is a scientific blood-testing facility that receivessamples from local hospitals and clinics. The blood samples are passed through severalautomated tests, and the results are printed through a central computer that readsand stores the information about each sample that is tested.

Management is concerned about the quality of the service it provides and wants toestablish quality-control limits as a measure for the quality of its tests. Such managerialpractice is viewed as significant, because incorrect analysis of a sample can leadto a wrong diagnosis by the physician, which in turn might cost the life of a patient.

For this reason, 100 blood samples were collected at random each day after they hadgone through testing. After retesting was performed manually on this sample, theresults were:

The title is particularly important as it will get people to stop and listen. 2) Introductory part: This informs the reader of the problem or situation and the context you are interested in. The goal is to give the viewers some basic academic information they can use to evaluate the significance of the research proposal. 3) Rationale for this study. – What is the research issue?- Why is it an issue?- Why is it an issue now?- What could this research shed light on? You have to introduce the topic and clarify the significance of what you are trying to present. That is, you have to present research questions with a logical sequencing of facts. You have to give examples to illustrate your rationale. Be sure to have a conclusion that summarises your take-home message (why is it an issue now? what could this research shed light on?). Your introduction should be constructed so that it presents the desired information in a self- explanatory manner. You have to think of the introduction as a highly efficient, organised document upon which appear synopsis of the relevant information you want to convey (what is the research issue?), Just enough to get your point across. 4) Include references: You are required to identify previously conducted research in the area that you are focusing on. These sources need to be referred within your rationale section. Make it clear that you know what has been done in your area in the past and where your research will fit in. 5) Format: You have to make your introduction appealing. Simplify and include only relevant information. Be attentive to the structure and placement of your content. Write clearly. Make sure your introduction includes complete sentences and accurate spelling and punctuation. I hope it is clear now. I have attached a sample mark sheet as well so that you know how marks are…
