论文摘要
当调查现实世界中的集体行为时，通过时间的成本会发挥重要作用。每个理性的人都可以通过全面考虑时间成本来获得更合理的策略。出于事实的启发，我们在这里提出了一种具有个人时间成本异质性的机制，其核心在两个方面：1。规则网络中的个人分为两组：高时间成本和低时间成本。 2。每个人都具有时间成本参数，并且当个人与邻居互动时，这些人会考虑到时间成本对收益的影响。同步更新算法用于研究常规晶格的时间成本的合作演变。仿真结果表明，提出的机制有效地促进了雪地拖运游戏的合作。此外，据表明，以下原因导致了较高的合作水平：较高的时间成本，小组中的高空成本越多，当低时间成本保持不变时，团体之间的时间成本越多。
Cost of time passing plays an important role when investigate the collective behaviour in real world. Each rational individual can get a more reasonable strategy by comprehensively considering the time cost. Motivated by the fact, we here propose a mechanism with individual time cost heterogeneity whose core lies in two aspects: 1. The individuals in the rule network are divided into 2 groups: high-time cost and low-time cost. 2. Each individual is endowed with a time cost parameter, and the individuals take into account the effect of time cost on the benefit when they interact with a neighbour. The synchronous updating algorithm is used to study the evolution of cooperation with time cost on a regular lattice. Simulation results show that the proposed mechanism effectively promotes cooperation in the snowdrift game. Moreover, it is revealed that the following reasons lead to a higher level of cooperation: The higher time cost, the more individuals of high-time cost in the group, and the more differences of time cost between groups when low-time cost remains unchanged.
