WebSummary: An interective demo of my proof for containing the 1-pyro, an extension of the firefighting problem. In the Firefighter Problem, a fire begins on a single vertex on a graph and expands to every unprotected adjacent vertex on each of it's turns. After each of the fire's turns, a firefighter can protect some set number, n, of vertices. WebWe provide approximation algorithms for several variants of the Firefighter problem on general graphs. The Firefighter problem models the case where an infection or another diffusive process (such as an idea, a computer virus, or a fire) is spreading through a network, and our goal is to stop this infection by using targeted vaccinations.
