中文简介:
利他主义在人类中引起非常强烈和多样的感情。它的矛盾性使它变得神秘和难以理解。很难理解为什么一个理性的人会为别人牺牲自己的利益,特别是如果一个人的生殖能力依赖于他们的话。也很难相信这种特性会在自然选择中存活下来。事实上,在广泛的条件下,严格的定理证明了纳什稳定策略是自私的,而不是分享的。我们发现,资源共享的表现型是非常受欢迎的,如果玩家不产生固定的收益和损失,而是获得或失去其现有资源的固定部分,那么自然选择就会大大获胜。因此,共享悖论的解决办法在于认识到现实生活、社会、经济和文化博弈的随机乘性(而不是通常的博弈论加性)。在本文中,我将介绍模型不同变化的分析和数值结果,以及支持和澄清这些结果的强化计算机模拟结果。
课程简介: Altruism elicits in humans very powerful and diverse feelings. Its paradoxical nature makes it mysterious and challenging to understand. It is difficult to understand why a rational being would sacrifice its own interests for somebody else, especially if one's reproduction fitness depends on them. It is also difficult to believe that such a trait would survive natural selection. In fact it was shown by rigorous theorems in a wide range of conditions that the Nash stable strategy is to be selfish and not to share. We show that the resources sharing phenotype is highly favored and wins natural selection dramatically if instead of incurring fixed gain and losses, the players gain or loose fixed fractions of their current resources. Thus the solution of the sharing paradox resides in recognizing the random multiplicative (rather then the usual game-theory "additive") character of the real life, society, economic and cultural "games". In this talk I will present analytical and numerical results for different variations of the model along with results from intensive computer simulations that support and clarify these results
关 键 词: 自然选择; 资源共享型; 随机乘法
