A new, efficient algorithm for the Forest Fire Model
The Drossel-Schwabl Forest Fire Model is one of the best studied models of
non-conservative self-organised criticality. However, using a new algorithm,
which allows us to study the model on large statistical and spatial scales, it
has been shown to lack simple scaling. We thereby show that the considered
model is not critical. This paper presents the algorithm and its parallel
implementation in detail, together with large scale numerical results for
several observables. The algorithm can easily be adapted to related problems
such as percolation.Comment: 38 pages, 28 figures, REVTeX 4, RMP style; V2 is for clarifications
