CS4102 Algorithms - Spring 2019

Course Description: Introduces the analysis of algorithms and the effects of data structures on them. Algorithms selected from areas such as sorting, searching, shortest paths, greedy algorithms, backtracking, divide-and-conquer, and dynamic programming. Data structures include heaps and search, splay, and spanning trees. Analysis techniques include asymptotic worst-case, expected time, amortized analysis, and reductions between problems

Availability: It is important to me to be available to our students, and to address their concerns. If you cannot meet with me during our office hours, e-mail me and we will find the time to meet. That being said, like everybody else I am quite busy, so it may take a day or more to find a time to meet. And if you have any comments on the course—what is working, what is not working, what can be done better, etc.—I am very interested in hearing about them. There is an anonymous feedback tool through Collab, or you can send me or one of the TAs an e-mail. We tend to get bogged down by e-mail as the semester progresses, so seeing us in person (right after lecture, during office hours, etc.) is often a good way to get a more immediate response.

We will attempt to keep to this schedule throughout the semester. As we go through the semester, I will add homework dates.
