我们研究了近视的最佳反应动力学下的社会困境的合作出现的接触网络的效果。我们开始总结在智力要求不高的动态下观察到的主要特征，指出它们最相关的一般特征。随后，我们重点讨论了最佳对策的新框架。通过一个广泛的数值模拟程序，我们表明，相反，到目前为止考虑的其他动力学，最佳对策基本上不受底层网络的影响，这意味着，在大多数情况下，没有促进合作，发现与此动态。然而，我们发现，非平凡的结果不同于良好的混合人口的情况下，协调游戏的格子，我们解释的空间集群的形成和他们的进步的条件，随后讨论他们的相关性，其他网络。
We study the effect of a network of contacts on the emergence of cooperation on social dilemmas under myopic best response dynamics. We begin by summarizing the main features observed under less intellectually demanding dynamics, pointing out their most relevant general characteristics. Subsequently we focus on the new framework of best response. By means of an extensive numerical simulation program we show that, contrary to the rest of dynamics considered so far, best response is largely unaffected by the underlying network, which implies that, in most cases, no promotion of cooperation is found with this dynamics. We do find, however, nontrivial results differing from the well-mixed population in the case of coordination games on lattices, which we explain in terms of the formation of spatial clusters and the conditions for their advancement, subsequently discussing their relevance to other networks.
