 Implement Gale-Shapley Algorithm for computing Stable Marriage Assignment in any language, such as Python, Java, C++ or MATLAB, using the approach and data structures described in the first two Chapters of the Kleinberg and Tardos text. The input file should include number of subjects, n, preference list for men and women one line for each. n m1: w11, w12, …, w1n … … mn: wn1, wn2, …, wnn w1: m11, m12, …, m1n … … wn: mn1, mn2, …, mnn a) Write a function to create preference lists for men and women. Function should take number of men (women), say n, create preferences and output them. b) Write the output, explicitly checking to see that it is a stable match (It requires a separate function to check). Turn in sample inputs and corresponding outputs in separate files. c) Run the algorithm on several instances of the problem for n = 10 with different input files and plot the variation in the running time. d) Run the algorithm on several instances of the problem for n = 10 with the same input file and plot the variation in the running time. e) Run the algorithm on problem instances with n = 10, 15, 20, 50, 100, and plot the average running time as a function of the problem input size (n). f) Run the algorithm on several instances of the problem for n = 10 with the same input file, let a different man start proposing and output the matches. 

 Subject :  InfoTech in a Global Economy  

it is a priority that students are provided with strong educational programs and courses that allow them to be servant-leaders in their disciplines and communities, linking research with practice and knowledge with ethical decision-making. This assignment is a written assignment where students will demonstrate how this course research has connected and put into practice within their own career.

 Assignment: 

Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of this course have been applied, or could be applied, in a practical manner to your current work environment. If you are not currently working, share times when you have or could observe these theories and knowledge could be applied to an employment opportunity in your field of study.  

Requirements:

Provide a 500 word (or 2 pages double spaced) minimum reflection.

Use of proper APA formatting and citations. If supporting evidence from outside resources is used those must be properly cited.

Share a personal connection that identifies specific knowledge and theories from this course.

Demonstrate a connection to your current work environment. If you are not employed, demonstrate a connection to your desired work environment. 

You should not, provide an overview of the assignments assigned in the course. The assignment asks that you reflect how the knowledge and skills obtained through meeting course objectives were applied or could be applied in the workplace. 

Do not use prior assignments in the completion of this activity. This is specific to the concepts presented in ITS832 and how you will use them or do use them in your professional lives.

Payroll Lab

You will be taking in a file (payroll.txt) which details a number of departments (at least 1) and in each department are a set of employees (each department will have at least 1 employee or it would not appear on the payroll sheet). Your job is to read the file in separate out each employee and calculate the total values (hours, salary, number of employees) for each department and in each category (F1, F2, F3, F4). In your final submission please include the .cpp file which should work for any kind of payroll file I supply (which will naturally match the format of the examples below). Be sure to indicate in your submission text if you have attempted any of the bonus points .

An example file:

The IT Department
Bill 8 7 8 9 7 F1
Bob 205103 0.08 F3
Betty 8 8 7 8 8 F2
Brandon 10 10 9 6 9 F2
Brad 9 8 10 9 9 4 1 F4

The Sales Department
Kyle 88840 0.105 F3
Tyler 105203 0.085 F3
Konner 8 6 7 6 9 F2
Sam 309011 0.045 F3
Kent 9 8 9 9 9 0 0 F4

An additional example file:

The Sales Department
Mike 5 6 1 3 5 F1
Mark 98103 0.115 F3
Jill 8 8 8 8 8 F2

Frank 106101 0.095 F3

Mark 76881 0.091 F3

Department of Records
Konner 8 6 7 6 9 F2
Tammy 7 3 7 2 8 F1

Anika 8 8 8 8 8 F2

Last in the row after the hours comes the pay grade (F1, F2, F3, F4). The number of hours recorded is based on the pay grade of the employee. F1 and F2s will have 5 numbers for their hours. F3s are commission based where a sales amount and a commission percentage is given. F3s are also assumed to work 30 hours if their commission is 10% or below and 40 hours if their commission is above 10%. F4s will have 7 numbers (as they are on-call during the weekend). Each of the pay grades will also have different pay calculations which are as follows:

F1 = The total number of hours * 11.25
F2 = (The total number of hours – 35) * 18.95 + 400
F3 = The total sales amount * the commission rate
F4 = The first 5 hourly totals * 22.55 + Any weekend hourly totals (the last 2) * 48.75

Your output to the screen should start with the department name, followed by the total pay for all of the employees, then the total number of hours, and the total number of employees. After that you should have a breakdown of each category of employee: F1 total pay and total hours, F2 total pay and total hours…

Each department will have at least 1 employee and each department will contain the word “Department.”

Before coding your solution, take the time to design the program. What are the possible things that the file can have that you need to anticipate? What are the actions that you need to take (read the file, add up hours…)? Are those actions things that could be placed in separate functions? What about the function – can you guess some of the things that will happen? Such as, using substring to pull out part of a line in the file maybe using stoi to convert a string to an integer to add it to the total or creating variables to hold the employee type you find before passing it to another function. Finally, how are these functions called, what is the order and what information is passed to and from? 

Scoring Breakdown

25% program compiles and runs
30% program reads in and calculates the figures for output
10% the program is appropriately commented
35% outputs the correct information in a clear format 

5% bonus to those who can output the F# responses in a columned output like that shown above.

5% order the employees in the roster according to their F status, F1’s first, then F2’s and so on.
5% bonus to those who do a chart comparing the data at the end to show the relation between the pay grades and the amount of salary spent in each (they style of chart is up to you and more points may be given for more difficult charts (like a line chart):

B Department
F1 – 00000000
F2 – 000000
F3 – 00000
F4 – 000000000000 

K Department
F1 – 0
F2 – 0000
F3 – 0000000000

What are some distinctions between COPPA and CIPA? Similarities?

Describe an organization that might be subject to both laws, and explain why you believe they both may apply.

Why do you believe that these two laws define “child” differently? Is it rational to do so?

Lastly, feel free to add further analyses or commentary that reflects your understanding of the two related but distinct laws.

Assignment Content

1. There are several tools and techniques featured in the textbook that are used for quality control in IT projects. A Pareto chart is a type of histogram that can be used to define quality problems in a system. It allows you to see what areas need improvement.

   Create a Pareto chart based on the information below. Use the Pareto Chart template. You can also do the math and create the graph in Excel, but people who do get it wrong more often than the ones who use the template. List the most frequent customer problems first. On the graph, it should be the tallest bar first, then the next largest, and so on. The second item in the graph, after the bars, is the cumulative line and it should always go up from left to right, all the way to 100%. If you see a dip in the line, your problems are not listed in the correct order. Check your entries so your resulting chart looks like the one in Figure 8-7 in the textbook.

   Customer Complaints; Frequency/Week
   Customer is on hold too long; 90
   Customer gets transferred to wrong area or cut off; 20
   Service rep cannot answer customer’s questions; 120
   Service rep does not follow through as promised; 40

   Submit your chart.
