优势策略和劣势策略的博弈论教学探讨

A Discussion on Teaching of Dominant Strategy and Dominated Strategy in Game Theory

在博弈论里,优势策略和劣势策略是相反相成的两个概念。但是,这两个概念的数学定义不对称,造成了理解上的困难和误区。文章创新性地从策略效果的角度讲解这两个概念,很好地破解这些理解上的困难和误区,为相关教学提供建设性的参考。

Dominant strategy and dominated strategy are a pair of opposite concepts in game theory.However,their asymmetric mathematical definitions bring difficulties and mistakes in understanding.This paper innovatively interprets these two concepts from the respective of strategy effect,which eliminates the corresponding difficulties and mistakes in understanding very well.Our finding provides a constructive reference for teaching in game theory.
