Title: COVID on infinite grids

Abstract:  (Joint with Barnett, Bond, Macias, Parnell, and Schoenfield) We use Hartnell’s model for virus spread on a graph. We propose a Containment Protocol which looks ahead two time steps to decide where to place vaccinations. We show that the protocol is near optimal for four well-studied infinite grids. We will ask the audience to help us find optimal solutions for a pentagonal grid. This talk will be accessible to all and we especially encourage students to join us.
