After a brief hiatus to sort things out due to the COVID-19 pandemic, the CombOpt reading group is continuing its “Research Interests” series in Spring term 2020.
This term our reading group will be exploring the various research interests of students and faculty working on problems related to combinatorial optimization. If you would like to present on your recent work or a paper you find interesting please let one of the organizers know. This is a great opportunity to learn what other people working in combinatorial optimization are studying and to encourage collaboration.
