群居动物经常面临在一个或多个替代资源地点之间进行选择的情况。这种集体决策的一个核心问题包括确定哪些人以及何时做出决策。这项关于蟑螂群体选择庇护所的实验和理论研究表明，在没有完美知识或领导力的情况下，平等个体之间的非线性互动动态可以产生选择。我们确定了一种简单的机制，可以在信息和信号有限且不比较可用机会的情况下做出决策。这种机制可以为群体个体带来最佳的平均收益。我们的模型指出了一个独立于动物物种的通用自组织集体决策过程。
Group-living animals are often faced with choosing between one or more alternative resource sites. A central question in such collective decision making includes determining which individuals induce the decision and when. This experimental and theoretical study of shelter selection by cockroach groups demonstrates that choices can emerge through nonlinear interaction dynamics between equal individuals without perfect knowledge or leadership. We identify a simple mechanism whereby a decision is taken on the move with limited information and signaling and without comparison of available opportunities. This mechanism leads to optimal mean benefit for group individuals. Our model points to a generic self-organized collective decision-making process independent of animal species.
