CSCI 6220/4030 Randomized Algorithms, Fall 2019


Randomized Algorithms are the state of the art in contemporary algorithm design. They are usually simple, sometimes even easy to analyze, and they work well in practice. This course provides an introduction to basic concepts in the design and analysis of randomized algorithms.

Instructor: Alex Gittens (gittea at rpi dot edu)

Lectures: MTh 10am-11:50am; Greene 120

Office Hours: MTh 12pm-1pm, or by appointment; Lally 316

Course Text: (Recommended, not required) Probability and Computing, by M. Mitzenmacher and E. Upfal.

Grading Criteria:

Students are expected to have writing supplies on hand in each class to complete the in-class pop quizzes. If you are an athlete or for some other reason are not able to attend each class, make alternative arrangements with the instructor in the first two weeks of the course.

Letter grades will be computed from the semester average. Lower-bound cutoffs for A, B, C and D grades are 90%, 80%, 70%, and 60%, respectively. These bounds may be moved lower at the instructors discretion.


We will largely follow Mitzenmacher and Upfal, replacing the more ML-focused content with alternative material.

Lecture Schedule


All assignments must be typed (preferably in LaTeX) and are due at the start of class (defined as the first 10 minutes). Late assignments will not be accepted, unless you contact the instructor at least two days before the due date to receive a deferral. Deferrals will be granted at the instructor’s discretion, of course.


In teams of two to three individuals, you will give a 20 minute presentation of an interesting or cool result or an algorithm (or class of algorithms) from a course-relevant technical or survey paper to the class; if your research is relevant, that could also be the topic of your presentation. This can be material that requires no background beyond general knowledge of CS, or more niche/applied knowledge; in the latter case, you should quickly explain the relevant concepts and background. See the "Giving Talks" and "Reading Papers" slide decks from the CS RPI Graduate Skills Seminar.
