CSCI 570 – Analysis of Algorithms Homework 1 Due: June 6, 2008 Solutions 1. (5 points) problem 1 from chapter 1 Solution: False . E.g. n = 2. m 1 prefers w 1 and m 2 prefers w 2 . But w 1 prefers m 2 and w 2 prefers m 1 . There are two possible matchings, both stable. In one of them, no woman is happy. In the other, no man is happy. In particular, in neither matching is there a pair ( m, w ) such that m prefers w and w prefers m . 2. (5 points) problem 2 from chapter 1 Solution: True . Suppose not. Then we will argue that the matching S is not stable. This follows because both m and w prefer each other to their current partners, causing an instability. 3. (10 points) problem 3 from chapter 1 Solution: No, there isn’t always a stable pair of schedules. Here is an example showing why.

In this case, Network A wins both time slots. However, this matching is not stable. This is because, Network B can unilaterally change its own schedule, to go to matching 2, winning more time slots Matching 2 : Lost v/s Entourage and House MD v/s Heroes. Network A wins the second slot. Network B wins the ﬁrst slot. This matching is not stable either, because Network A can unilaterally change its own schedule to go to matching 1, winning more time slots. 2...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
