Abstract

Cellular automata offer excellent modeling paradigms for the study of global behavior from local interactions. Instead of focusing on a physical model of forest fires, this paper considers possible models of artificial ones with the point of view of global parameters given local interactions rules. A set of possible rules for fire ignition, is assumed for the purpose of local interactions. These examine the empirical results and enquire if there are critical densities for various kinds of initial configurations and rules of interactions. It is found that there exists the association between λ 99, the parameter developed in this study, and the rules set. This leads to the certain relationship among an initial density of a dynamic state of a forest, a global phenomenon, and a local interactions.
