Algorithms and Uncertainty (24h, 3 ECTS)

☝ This course is suspended during the academic year 2022/2023.

Course Outline

In many settings such as routing calls in a network, scheduling jobs in processors, or even trading in the stock market, the decision-maker operates in a status of uncertainty. The objective of the course is to study algorithmic models, techniques, analyses, and approaches that have been developed specifically for dealing with this class of problems. The course is will be focused on the following specific aspects of computation under uncertainty:

  1. Online algorithms, in which the input is not known ahead of time;
  2. Regret minimization and online optimization in machine learning; and
  3. Recently introduced frameworks such as algorithms with predictions, and algorithms with explorable uncertainty.

The course will focus on the analytical/theoretical analysis of algorithms with uncertainty, but also on concrete applications.

Grading scheme and homework policy

Grading scheme: 50% from the final exam, and 50% from weekly homeworks.

Homework policy: Homeworks are due at the beginning of class. No late homework will be accepted, except for serious reasons (please notify the instructors in time). You should not collaborate with other students, and should not search the internet for similar problems. If you end up using any material outside notes, you must acknowledge your sources.

EXAM INFORMATION The exam will take place during the regular course hours on Friday, December 3rd. You are allowed to bring the handwritten notes you took during the class, printout of course slides, and papers that we have uploaded on the course web page. The following are NOT allowed: books, any papers other that those on the course web page, homework solutions.


We will propose internships early in the course. We urge all students who are interested to talk to the instructors as soon as possible. The internships will be related to the topics of research of the instructors and the lectures given in the course, or, more broadly, to the research interests of the instructors.
