Evolutionary snowdrift game with loners

摘要:

在一个完全混合的种群或全连通网络和一个正方形格子中,研究了雪堆博弈中一个被称为孤独者的额外策略或角色的影响。在研究竞争种群中的合作现象时,雪堆博弈是囚徒困境博弈的一种可能的替代方案,它由两种类型的策略组成,C(合作者)和D(背叛者)。在一个完全连通的网络中,发现要么C和D生活在一起,要么孤独者接管整个群体。在一个正方形格子中,我们发现了三种可能的情况:一个均匀的C-种群,C与D共存,以及所有三个字符共存。孤独者的存在下,发现在一个正方形晶格中,通过提高合作者的收益,以提高合作。结果进行了讨论的影响,限制一个球员只与他最近的邻居在一个正方形格子,而不是与所有球员在一个完全连接的网络竞争。

英文摘要:

The effects of an additional strategy or character called loner in the snowdrift game are studied in a well-mixed population or fully-connected network and in a square lattice. The snowdrift game, which is a possible alternative to the prisoner's dilemma game in studying cooperative phenomena in competing populations, consists of two types of strategies, C (cooperators) and D (defectors). In a fully-connected network, it is found that either C lives with D or the loners take over the whole population. In a square lattice, three possible situations are found: a uniform C-population, C lives with D, and the coexistence of all three characters. The presence of loners is found to enhance cooperation in a square lattice by enhancing the payoff of cooperators. The results are discussed in terms of the effects in restricting a player to compete only with his nearest neighbors in a square lattice, as opposed to competing with all players in a fully-connected network.
