An advertising company underwent a thorough reorganization during which the m employees of the department of creative designers got laid off. however n > m new positions have been created in the company. the human resources manager interviews all m employees regarding their interest in the positions and their qualifications. then he assigns a score sij to each employee i for each position j they are willing to accept reflecting how qualified employee i is for position ; the goal of the manager is to assign jobs to employees so that the sum of the scores of the employees who are assigned to jobs is maximized. a single job cannot be assigned to more than one employee and a single employee may not be assigned to more than one job. i. (4 points) formulate an integer program (ip) for this problem. ii. (4 points) formulate this problem in graph-theoretic terms and explain what the above ip finds. iii. (4 points) now suppose that sij = 1 for every employee i that qualifies for a job j. explain in graph-theoretic terms what the resulting ip finds. iv. next consider the specific instance of the above problem where m = 2, n = 3, sij = 1 for all 1

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
