Cemetery Formation in Ant Colonies

Bastien Chopard presented a model of cemetery formation in ant colonies. He showed that cemetery formation is not a collective behaviour, since one ant can achieve the same result, only slower. Instead, cemetery formation is the effect of the fluctuation of cluster sizes and the fact that a cluster of zero size has disappeared and cannot reappear. Here we show a similar model, in which cluster formation can also be observed, although not usually to the point of having only one cluster left. The description is fairly complicated, since the asynchronous behaviour is simulated by using a synchronous three-step rule. The file is Ants.cdl and the simulation starts automatically.
