从演化的视角对纳什均衡所在的策略空间做了一个观察,认为纳什均衡所在的策略空间是不断变化的,这种变化源于策略空间本身的变化而不是决策,并以“生产力”与“生产关系”的类比对此给出了一种解释.通过“囚徒困境”中策略空间的演化进一步说明了演化的必然性,同时得到决策是基于所处的策略空间演化过程中的位置的结论,相应的策略空间中的某个纳什均衡并不能成为一种持续的决策所依赖的均衡.
從縯化的視角對納什均衡所在的策略空間做瞭一箇觀察,認為納什均衡所在的策略空間是不斷變化的,這種變化源于策略空間本身的變化而不是決策,併以“生產力”與“生產關繫”的類比對此給齣瞭一種解釋.通過“囚徒睏境”中策略空間的縯化進一步說明瞭縯化的必然性,同時得到決策是基于所處的策略空間縯化過程中的位置的結論,相應的策略空間中的某箇納什均衡併不能成為一種持續的決策所依賴的均衡.

From the perspective of evolution, the strategy space including a certain Nash Equilibrium is changing constantly. And the constant change is originated from nothing but itself, which has been explained by analogy with the relationship of productive forces and production relations in this paper. And then the paper further illustrates the inevitability of evolution by showing the dynamic change course of the strategy space concerning Prisoner's Dilemma. Conclusions gained are as follows: decision-making is based on some unique course which contains future uncertainty, so a certain Nash Equilibrium in the strategy space is not the sustained or crucial factor for decision-making.
