基于信念的进化稳定策略

A belief-based evolutionarily stable strategy

Xinyang Deng, Zhen Wang, Qi Liu, Yong Deng, Sankaran Mahadevan

摘要:

进化稳定策略作为纳什均衡的一种均衡改进,是进化博弈论中的一个重要概念,引起了人们越来越多的关注。ESS可以是纯策略,也可以是混合策略。尽管混合策略允许随机性,但由于多种因素的影响,混合策略中纯策略的选择概率可能会发生波动。波动可能导致更多的不确定性。本文进一步考虑了混合策略中的不确定性,提出了一种基于Dempster-Shafer证据理论的信念策略。此外,基于所提出的信念策略,基于信念的ESS已被开发。信念策略和基于信念的进化支持系统可以归结为混合策略和混合进化支持系统,为描述Agent之间的交互提供了更真实、更有力的工具。

英文摘要:

As an equilibrium refinement of the Nash equilibrium, evolutionarily stable strategy (ESS) is a key concept in evolutionary game theory and has attracted growing interest. An ESS can be either a pure strategy or a mixed strategy. Even though the randomness is allowed in mixed strategy, the selection probability of pure strategy in a mixed strategy may fluctuate due to the impact of many factors. The fluctuation can lead to more uncertainty. In this paper, such uncertainty involved in mixed strategy has been further taken into consideration: a belief strategy is proposed in terms of Dempster-Shafer evidence theory. Furthermore, based on the proposed belief strategy, a belief-based ESS has been developed. The belief strategy and belief-based ESS can reduce to the mixed strategy and mixed ESS, which provide more realistic and powerful tools to describe interactions among agents.
