The Forest-Fire Model — Tuning and Universality

  • Stefan Hergarten


We continue our introduction into the ideas of SOC with the forest-fire model and a discussion on tuning parameters and SOC systems in non-equilibrium. A first version of this model was published by Bak et al. (1990), but Drossel and Schwabl (1992) were the first to discover SOC uniquely in a modified approach. Although it is even simpler than the BTW model (Sect. 5.2), the forest-fire model has some relevance to nature as the sizes of real forest fires exhibit power-law statistics to some degree (Malamud et al. 1998).
