论文摘要
累积文化进化是使人类在各种生态和人口环境中蓬勃发展的原因。可以将人类需要解决的任务的解决方案映射到可以采用封闭或开放式健身景观形式的任务空间，而在文化进化研究中，前者的建模比后者更广泛。在本文中，我们修改了Arthur and Polak（2006）的模拟，该模拟通过使用计算机模拟来建立开放式健身景观，该计算机模拟构建了逻辑电路，该电路与早期试验中构建的电路。我们使用此仿真来阐明开放式健身景观的性质，并研究培养速度是否通过增加的群体规模来提高。结果表明，群体大小提高了积累速度，但比预期的有限。同样，当两种类型的积累，发明和改进时，都区分了两者的性质。在改进中，轨迹遵循凸功能，随着群体大小的增加，一个药物的生产力降低。在发明中，该轨迹显示出迅速增加的连续模式，其次是高原。
Cumulative cultural evolution is what made humanity to thrive in various ecological and demographic environments. Solutions to the tasks that humans needed to solve could be mapped onto a task space which could take the form of either closed or open-ended fitness landscape, with the former being modeled more extensively than the latter in studies of cultural evolution. In this article, we modified a simulation by Arthur and Polak (2006) that modeled open-ended fitness landscape by using a computer simulation that builds logical circuits with circuits that were built in earlier trials. We used this simulation to clarify the nature of open-ended fitness landscape and to investigate whether the speed of accumulation of culture is increased by an increase in group size. The results indicated that group size increased the speed of accumulation but is limited than expected. Also, when two types of accumulation, invention and improvement, were distinguished the nature of the two differed. In improvement, the trajectory followed a convex function with productivity of one agent decreasing as group size increased. In invention, the trajectory showed a continuous pattern of rapid increase followed by a plateau.
