Web1 de set. de 2024 · Firefighter is a discrete-time dynamic process that models the spread of a virus or rumour through a network. 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”.
