CS 515: Algorithms and Data Structures (Fall 2017)
Instructor:
Amir Nayyeri (Office hours: Wed 23pm at KEC 3061)
TA:
Marjan Adeli (Office hours: Tue 2:303:30pm at KEC Atrium)
Lectures: Tue, Thr 18:0019:20 in KEAR 212
Tentative topic list: Recursive algorithms, Dynamic programming, Greedy algorithms, Randomized algorithms and data structures, Treaps, Hashing*, Network flow, Linear programming, Approximation algorithms*.
Prerequisites: Graduate standing in computer science and an undergraduate course in algorithms. I assume that the students are comfortable with CS325 material. (If you have not taken any undergraduate algorithm course, I strongly recommand taking CS519005 before this course.)
