| 摘 要： | 以往对演化博弈的研究都假设个体从博弈中获得的支付是确定的并以精确的数来表示。然而由于受环境中各种不确定因素的影响,个体博弈时所获得的支付并不是一个精确的数值,而需要用一个模糊数来表示。本文研究模糊支付下2×2的对称博弈, 利用模糊数的运算, 分析具有模糊支付的有限种群Moran过程演化动态。在弱选择下以梯形模糊数和三角模糊数表示博弈支付,计算策略的模糊扎根概率,分析自然选择有利于策略扎根及策略成为模糊演化稳定策略的条件。将经典博弈推广到模糊环境中丰富了演化博弈理论,更具有现实意义。

| Abstract: | Previous studies on evolutionary game dynamics have assumed that individuals’ rewards from the game are expressed in exact numbers. However, because of the influence of the various factors from the environment, the payoff obtained by individuals’ interaction is not an exact number. The payoff can be represented by fuzzy numbers. We study 2×2 symmetric games in which the game matrix is represented by fuzzy numbers. The fuzzy fixation probability of the strategy based on fuzzy game matrix is calculated by using the operation relation of fuzzy numbers. In the form of triangular fuzzy number and trapezoid fuzzy number, numerical analysis is carried out. Numerical examples demonstrate the feasibility and validity of the new method. We obtain the conditions that natural selection is favorable for a strategy to take fixation and a strategy to be a FESS. It is more realistic to promote the classical game to the fuzzy environment and also enrich the theory of evolutionary game. |
