Papers from the Theory of Computing Group Accepted to SODA 2020

About

The group does research on the fundamental capabilities and limitations of efficient computation.

In addition, they use computation as a lens to gain deeper insights into problems from the natural, social, and engineering sciences.

The group is highly collaborative, both within Columbia and among peer institutions. They hold a weekly Theory Lunch and a bi-weekly Student Seminar. Most graduate students have (at least) two advisors and collaborate with several professors and other students. Some of the faculty are cross-listed with the IEOR department and the Data Science Institute.
