涡旋状群集行为在广泛的生物系统中被观察到。在这里报道的工作中，离散粒子模型被用来调查发病的相互作用的粒子群中的这种涡状行为。粒子群的总有效能量的约束最小化进行，与总角动量的群体保守。结果表明，涡状行为的出现，然后可以被看作是一个受约束的最小能量配置的群放松。
Vortexlike swarming behavior is observed in a wide range of biological systems. In the work reported here a discrete particle model is used to investigate the onset of such vortexlike behavior in a swarm of interacting particles. A constrained minimization of the total effective energy of the swarm of particles is performed, with the total angular momentum of the swarm conserved. It is shown that the emergence of vortexlike behavior can then be viewed as a constrained minimum energy configuration which the swarm relaxes into.
