Math Encounters:

"Optimal Tours: The Traveling Salesman Problem" with Bill Cook

Wednesday, August 4 at 4:00 pm ET (New York)

In person!

Is it possible to compute the shortest route through a large number of stops?  It sounds simple, but finding a method that can do this quickly for every example would be a stunning breakthrough in mathematics — and would earn you a million-dollar prize.  Join mathematician Bill Cook as we explore the history and applications of this fascinating challenge, and examine state-of-the-art approaches to solving it.

Special introduction by Alex Kontorovich, MoMath’s 2020-2021 Distinguished Visiting Professor for the Public Dissemination of Mathematics and Rutgers math professor.

This event will take place in person at MoMath at 11 East 26th Street.

All in-person seats are available on a first-come, first-served basis.

All patrons are required to wear masks while visiting the Museum.

Please arrive 15 to 30 minutes before the event to complete registration.

This event is free, but a $25 donation will help MoMath defray reopening costs as patrons are welcomed back to the physical Museum.
