扩大学习范围对无标度网络中合作演化的影响
Effect of expanding learning scope on the evolution of cooperation in scale-free networks
AI总结：
本文研究无标度网络公共物品博弈中扩大博弈与学习对象选择范围对合作演化的影响，发现扩大博弈范围抑制合作，而扩大学习范围在合作难演化时促进合作，并揭示了不同于中心节点机制的新机制。
AI中文摘要：
我们研究扩大博弈对象与学习（适应）对象的选择范围如何影响无标度网络上公共物品博弈中合作的演化。我们得到以下三个结果。（i）扩大博弈对象的选择范围会抑制合作。（ii）当合作演化较为困难时，扩大学习对象的选择范围会促进合作。（iii）当合作更可能演化时，略微扩大学习对象的选择范围会导致合作率显著下降，但进一步扩大选择范围会使合作率回升。虽然（i）可由中心节点机制解释，即在无标度网络上促进合作的著名动力学机制，但（ii）和（iii）是由一种完全不同的、迄今为止很少被提及的机制所导致。
英文摘要：
We study how expanding the scope for selecting game and learning (adaptation) partners affects the evolution of cooperation in public goods games on scale-free networks. We show the following three results. (i) Expanding the scope for selecting game partners suppresses cooperation. (ii) Expanding the scope for selecting learning partners promotes cooperation when cooperation evolution is difficult. (iii) When cooperation is more likely to evolve, slightly expanding the scope for selecting learning partners causes a significant drop in the cooperation rate, but expanding the scope further causes the cooperation rate to recover. Although (i) is explained by the hub-centered mechanism, the well-known dynamic that promotes cooperation on scale-free networks, (ii) and (iii) are caused by a completely different mechanism that has heretofore been rarely mentioned.
