论文摘要
我们研究了一个空间，单枪囚犯的困境（PD）模型，其中选择在有机体的行为策略（合作或缺陷）上进行，及其在一组离散的时间段中实施该策略的选择。当我们将时间插槽添加到晶格和小世界网络中时，合作者会定期固定在模型中，并且当生物体在无标度网络中相互作用时，它们的一部分人口会增长。这种合作者的选择发生在各种各样的时间段中，即使违反了在图表上进行合作演变的关键条件，也违反了PD的福利与成本之比不超过空间相邻的生物体的数量。
We study a spatial, one-shot prisoner's dilemma (PD) model in which selection operates on both an organism's behavioral strategy (cooperate or defect) and its choice of when to implement that strategy across a set of discrete time slots. Cooperators evolve to fixation regularly in the model when we add time slots to lattices and small-world networks, and their portion of the population grows, albeit slowly, when organisms interact in a scale-free network. This selection for cooperators occurs across a wide variety of time slots and it does so even when a crucial condition for the evolution of cooperation on graphs is violated--namely, when the ratio of benefits to costs in the PD does not exceed the number of spatially-adjacent organisms.
