Erdos-Renyi随机图+森林火灾=自组织临界性

Erdos-Renyi random graphs + forest fires = self-organized criticality

Balazs Rath, Balint Toth

摘要:

我们修改通常的Erdos-Renyi随机图的演变,让连接的集群“烧毁”(即分崩离析断开单个网站),由于闪电的泊松流。在一定的闪电强度和闪电频率范围内,系统始终处于临界状态。

英文摘要:

We modify the usual Erdos-Renyi random graph evolution by letting connected clusters 'burn down' (i.e. fall apart to disconnected single sites) due to a Poisson flow of lightnings. In a range of the intensity of rate of lightnings the system sticks to a permanent critical state.
