论文摘要
创新是人类进步的推动力。最近的urn模型很好地重现了新颖性发现的动态，在不断扩大的机遇中，却忽略了社交互动的影响。在这里，我们专注于集体探索的机制，并提出了一个模型，其中许多代表不同探索者的ur依通过社交网络的联系并利用他们的接触机会来利用机会。我们在分析和数字上研究了不同的网络结构，即发现探险家的速度取决于其在社交网络中的中心地位。我们的模型阐明了社会结构在发现过程中的作用。
Innovation is the driving force of human progress. Recent urn models reproduce well the dynamics through which the discovery of a novelty may trigger further ones, in an expanding space of opportunities, but neglect the effects of social interactions. Here we focus on the mechanisms of collective exploration and we propose a model in which many urns, representing different explorers, are coupled through the links of a social network and exploit opportunities coming from their contacts. We study different network structures showing, both analytically and numerically, that the pace of discovery of an explorer depends on its centrality in the social network. Our model sheds light on the role that social structures play in discovery processes.
