要理解组织良好的社会行为的演变，我们必须首先理解集体行为建立的机制。在这项研究中，在一个群体的社会昆虫的集体行为的机制进行了研究，在活跃和不活跃的状态之间的转换概率，这是相互作用。社会昆虫的活动和不活动状态的统计提取的速度剖面。从两个态的持续时间分布中，我们发现：（1）活性态和非活性态的持续时间遵循指数规律;（2）对相互作用增加了从非活性态到活性态的跃迁概率。对相互作用的转移概率的调节表明，这种相互作用控制着殖民地中活跃和不活跃的工蚁种群。
To understand the evolution of well-organized social behaviour, we must first understand the mechanism by which collective behaviour is established. In this study, the mechanisms of collective behaviour in a colony of social insects were studied in terms of the transition probability between active and inactive states, which is linked to mutual interactions. The active and inactive states of the social insects were statistically extracted from the velocity profiles. From the duration distributions of the two states, we found that (1) the durations of active and inactive states follow an exponential law, and (2) pair interactions increase the transition probability from inactive to active states. The regulation of the transition probability by pair interactions suggests that such interactions control the populations of active and inactive workers in the colony.
