We show that the intelligence of a swarm of cooperative units (birds) emerges at criticality, as an effect of the joint action of frequent organizational collapses and of spatial correlation as extended as the flock size. The organizational collapses make the birds become independent of one another, thereby allowing the flock to follow the direction of the lookout birds. Long-range correlation violates the principle of locality, making the lookout birds transmit information on either danger or resources with a time delay determined by the time distance between two consecutive collapses.
我们表明，一群合作单元（鸟类）的智能在临界点出现，这是频繁的组织崩溃和与鸟群大小一样延伸的空间相关性的共同作用的结果。组织崩溃使鸟类彼此独立，从而使鸟群能够跟随瞭望鸟的方向。长程相关性违反了局部性原则，使得瞭望鸟在危险或资源方面传递信息，其时间延迟由两次连续崩溃之间的时间距离决定。
