一维元胞自动机中的巴甫洛夫囚徒困境:解析结果、准正则相、时空模式和参数空间探索

Pavlovian Prisoner's Dilemma in one-dimensional cellular automata: analytical results, the quasi-regular phase, spatio-temporal patterns and parameter space exploration

Marcelo Alves Pereira, Alexandre Souto Martinez

摘要:

由于自私玩家之间合作的出现,囚徒困境(PD)游戏被应用于多个领域。在这里,我们考虑了一个一维的格子,其中每个单元代表一个参与者,可以合作或背叛。这个一维的几何形状使我们能够检索得到的结果,并保持跟踪系统的时空演变。玩家与他们的邻居进行PD游戏,并使用巴甫洛夫进化策略更新他们的状态。如果参与者得到的正收益大于期望值,他们会保持状态并转换状态,否则。我们得到了分析的临界诱惑值,我们提出了集群模式,出现从球员的本地相互作用,我们进行了探索的参数空间。数值结果与临界诱惑分析结果一致,证实了巴甫洛夫策略能促进局中人之间的合作,避免背叛。该系统还提出了一个新的阶段,在稳定状态,准定期阶段,其中几个球员切换他们的状态在一轮又一轮,但合作者的比例并没有显着改变。

英文摘要:

The Prisoner's Dilemma (PD) game is used in several fields due to the emergence of cooperation among selfish players. Here, we have considered a one-dimensional lattice, where each cell represents a player, that can cooperate or defect. This one-dimensional geometry allows us to retrieve the results obtained for regular lattices and to keep track of the system spatio-temporal evolution. Players play PD with their neighbors and update their state using the Pavlovian Evolutionary Strategy. If the players receive a positive payoff greater than an aspiration level, they keep their states and switch them, otherwise. We obtain analitycally the critical temptation values, we present the cluster patterns that emerge from the players local interaction and we perform an exploration of paramater space. The numerical results are in accordance to the critical temptation analitycal results, it confirms that the Pavlovian strategy foment the cooperation among the players and avoid the defection. The system also presented a new phase in the steady state, the quasi-regular phase, where several players switch their states during round to round, but the proportion of cooperators does not alter significantly.
