论文摘要
进化游戏理论已被证明是一个优雅的框架，为人口动态和人类行为提供了许多富有成果的见解。在这里，我们专注于行为可塑性的方面及其对人口发展的影响。我们认为在混合良好的无限和有限种群设置中只有两种策略的游戏。我们假设个人可能表现出行为可塑性，称为玩家的无能。我们研究了这种异质性对当地互动结果以及最终对全球竞争的结果的影响。例如，当考虑行为可塑性时，从选择的角度来看，以前统治的策略可以成为可取的。此外，它可以缓解在无限人群入侵中成功固定的条件。我们在囚犯的困境和雪花游戏的例子上展示了我们的发现，我们在这里定义了可以促进合作的条件。
Evolutionary game theory has proven to be an elegant framework providing many fruitful insights in population dynamics and human behaviour. Here, we focus on the aspect of behavioural plasticity and its effect on the evolution of populations. We consider games with only two strategies in both well-mixed infinite and finite populations settings. We assume that individuals might exhibit behavioural plasticity referred to as incompetence of players. We study the effect of such heterogeneity on the outcome of local interactions and, ultimately, on global competition. For instance, a strategy that was dominated before can become desirable from the selection perspective when behavioural plasticity is taken into account. Furthermore, it can ease conditions for a successful fixation in infinite populations' invasions. We demonstrate our findings on the examples of Prisoners' Dilemma and Snowdrift game, where we define conditions under which cooperation can be promoted.
