中文简介: | 动物群体的运动给我们提供了“复杂性”概念的一个最清楚的例子。动物之间简单的相互作用会产生某种有规律但同时又难以描述的模式。在本文中,我们首先讨论这些模型及其对羊群运动的预测。我们提供了关于信息如何在这些系统中传递的新结果。我们查看了最近对蝗虫和鸽子的实验,这些实验表明,在这些群体中看到的至少一些模式可以用这些模型中出现的相变和分叉来解释。特别地,我们观察蝗虫行进中的相变和鸽子决策中的对称性破缺。 |
课程简介: | The movement of animal flocks give us one of the clearest examples of the concept of 'complexity'. Simple interactions between animals lead to patterns that are somehow regular but at the same time difficult to characterise. In this paper we discuss first these models and their predictions about the movement of flocks. We provide novel results about how information is transfered in these systems. We look at recent experiments on locusts and pigeons which show that at least some of the patterns seen in these groups can be explained by the phase transitions and bifurcations that arise from these models. In particular, we look at a phase transition in the marching of locusts and symmetry breaking in the decision-making of pigeons. |
