Bak-Sneppen型模型的临界值
Critical values in Bak-Sneppen type models
摘要：
在Bak-Sneppen模型中，最低适应度粒子及其两个最近邻粒子在每个时间步长以均匀的（0，1）适应度分布更新。该模型提出了一个临界值，这取决于相互作用的标准（两个最近的邻居）和更新程序（统一）。在这里，我们计算一个或两个属性都改变的模型的临界值。我们研究了非均匀更新模型，随机邻居模型和二进制适应度模型，并获得了平均适应度和$p_c$的精确结果。
英文摘要：
In the Bak-Sneppen model, the lowest fitness particle and its two nearest neighbors are renewed at each temporal step with a uniform (0,1) fitness distribution. The model presents a critical value that depends on the interaction criteria (two nearest neighbors) and on the update procedure (uniform). Here we calculate the critical value for models where one or both properties are changed. We study models with non-uniform updates, models with random neighbors and models with binary fitness and obtain exact results for the average fitness and for $p_c$.
