Time: MWF 3-3:50 PM
Location: Online

Instructor: Avah Banerjee

Course description:
This course is designed to introduce graduate students to advanced algorithm design techniques and to the current state-of-the-art. The course will balance between breadth and depth with slight emphasis given to the former. We will cover variety of different topics without spending too much time on each.

Course Outcomes:
Exposure to state of the art in algorithm research. Learn how to select open problems. Model challenging real world problems and develop algorithmic solutions.

Some knowledge about algorithm design techniques and analysis tools are needed (e.g. CS 5200). Some background in probability theory will be useful.

There are no textbooks required for this course. However, we will use some of the following books as reference along with lecture notes, papers and other reading materials.
1. (CLRS) T. Cormen, C. Leiserson, R. Rivest, and C. Stein, Introduction to Algorithms, 3rd edition, (available online through MERLIN)
2. (ME) Michael Mitzenmacher and Eli Upfal, Probability and Computing, Cambridge University Press, 2005
3. (V) Vijay Vazirani, Approximation Algorithms, Springer. Reserved.
4. (AR) Allan Borodin and Ran El-Yaniv, Online Computation and Competitive Analysis, Cambridge University Press, 2005

[Project ideas]

Grading Policy:
1. (Homework 40%): There will be 4 homework. These must be done individually.
2. Scribing (30%): Each student will scribe 3 lectures.
3. Project (30%): Can be done either individually or in a group of 2. If you can solve an open problem or improve upon an existing solution in some non-trivial way then you will automatically get an A in this course.
[Late submissions are not accepted.]
