WebAbstract. The firefigther problem is a deterministic discrete-time model for the spread (and the containment) of fire on an undirected graph. Assuming that the fire breaks out at a predefined set of vertices, the goal is to save as many vertices as possible from burning. The same model has also been used in the literature for the simulation of ... small field monitor

The name “Firefighter” arises from the initial analogy being the spread of fire among the vertices of a graph. Given a graph G, the process begins at time t = 0 when one or more vertices of G spontaneously “catch fire”. 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. small field mice
