第一个应该是最后一个：选择驱动的少数成为多数
The first shall be last: selection-driven minority becomes majority
摘要：
世界各地都有街头示威。在里约热内卢，2013年6月/7月，他们的覆盖面超过100万人。同一城市的主要报纸\textit{O Globo}的一位愤怒的读者发表了一封信\cite{OGlobo}，信中陈述了许多社会问题，并回答了是或否。这百万街头示威者对一系列类似的社会问题有着共同的看法。但他们并没有在如此众多的会议中达成这一共识。早些时候，他们在不同的小团体中会面，其中一些人可能会被其他几个研究员说服改变主意。突然，一个宏观的共识出现了。许多其他的大的显化在最近的时代在世界各地广泛传播，并且应该在未来继续存在。有趣的问题是：（1）通过小群体会议中发生的局部变化，分布在某些群体中的二元选项意见如何随时间演变？（2）是否存在某种自然选择法则？在这里，我们通过基于代理的模型来解决这些问题。
英文摘要：
Street demonstrations occur across the world. In Rio de Janeiro, June/July 2013, they reach beyond one million people. A wrathful reader of \textit{O Globo}, leading newspaper in the same city, published a letter \cite{OGlobo} where many social questions are stated and answered Yes or No. These million people of street demonstrations share opinion consensus about a similar set of social issues. But they did not reach this consensus within such a huge numbered meetings. Earlier, they have met in diverse small groups where some of them could be convinced to change mind by other few fellows. Suddenly, a macroscopic consensus emerges. Many other big manifestations are widespread all over the world in recent times, and are supposed to remain in the future. The interesting questions are: 1) How a binary-option opinion distributed among some population evolves in time, through local changes occurred within small-group meetings? and 2) Is there some natural selection rule acting upon? Here, we address these questions through an agent-based model.
