简介：DeGroot模型一个经典模型到意见的学习一致在里面一组个人(代理人)。一致能在一些情形下面被完成。但是什么时候这个组到达一致与一条会聚的意见珍视哪个不是我们期望什么，怎么罐头我们干涉系统和变化会聚的价值？在这糊机制命名软控制首先在意见动力学被介绍当人口被给，进化统治时，指导组意见不被允许变化。根据软控制的想法，一或几个特殊代理人，叫的党羽，被增加并且与在原版的代理人组织的或几正常连接了。党羽行动并且被当作正常代理人。作者证明会聚的意见价值的变化被起始的意见和党羽的有影响的价值决定，以及党羽怎么与正常连接代理人。有趣、违反直觉的现象被发现：与更小的起始的意见价值增加一个党羽(或更大)与比原版会聚的意见价值剂量未必减少(或增加)在一些条件下面的会聚的意见价值。这些条件通过数学分析被给，他们被数字测试验证。当一个党羽被连接到不同正常时，作者也发现系统的集中速度变化代理人。我们的模拟证明它是断然与连接正常的度有关在没有规模的网络的代理人。

简介：这篇论文问一个新问题：我们怎么能控制集体行为组织ofself的多代理人系统？我们试着由建议新观点called'SoftControl'回答这个问题，它把存在代理人的本地规则放在系统。我们由案例研究显示出软控制的可行性。考虑简单却典型的分布式的multi-agentmodel由Vicsek等求婚了。为鸟结队：每个代理人以一样的速度，但是与基于它的自己的标题的一般水准用一条本地规则被更新的不同标题和它的邻居的标题移动。这个模型的大多数研究关于self-organizedcollective行为，例如标题的同步。我们想要由软控制在这个组的集体行为(标题)干涉。一个指定方法是增加一个特殊代理人，叫了一个“党羽”，它能被我们控制，但是被另外的代理人当作一个平常的代理人。我们为党羽构造一条控制法律以便它能同步整个组到一个客观标题。这条控制法律被证明是有效经分解并且数字地。注意软控制与分布式的控制的途径不同。在分布式的系统干涉是一个自然方法。它可以在复杂系统的控制上拿出许多有趣的问题和挑战。
