  skos:definition "Le modèle abélien du tas de sable (Abelian sandpile model (ASM)) est le nom plus populaire du modèle original de Bak-Tang-Wiesenfeld (BTW). Le modèle BTW a été le premier exemple découvert d'un système dynamique affichant une criticité auto-organisée. Il a été introduit par Per Bak, Chao Tang et Kurt Wiesenfeld dans un article de 1987. Trois ans plus tard, Deepak Dhar a découvert que le modèle du tas de sable BTW suit effectivement la dynamique abélienne et a donc appelé ce modèle comme le modèle du tas de sable abélien. Le modèle est un automate cellulaire. Dans sa formulation d'origine, chaque site sur une grille finie a une valeur associée qui correspond à la pente du tas.

BTW model was the first discovered example of a dynamical system displaying self-organized criticality. It was introduced by Per Bak, Chao Tang and Kurt Wiesenfeld in a 1987 paper.Three years later Deepak Dhar discovered that the BTW sandpile model indeed follows the abelian dynamics and therefore referred to this model as the Abelian sandpile model. The model is a cellular automaton. In its original formulation, each site on a finite grid has an associated value that corresponds to the slope of the pile. This slope builds up as \"grains of sand\" (or \"chips\") are randomly placed onto the pile, until the slope exceeds a specific threshold value at which time that site collapses transferring sand into the adjacent sites, increasing their slope. Bak, Tang, and Wiesenfeld considered process of successive random placement of sand grains on the grid; each such placement of sand at a particular site may have no effect, or it may cause a cascading reaction that will affect many sites.
