【摘要】 基于混沌变量的遍历性、随机性构造了变尺度的变异算子对解空间进行开发,借鉴家族优生原理和均匀设计的思想来构造了正交算子和均匀算子,同时引入正反馈机制来模拟个体在局部探索中的信息交流,形成了一种新的混合演化算法。在边坡最小安全系数搜索中的应用证明了本文算法的有效性。更多还原

【Abstract】 Based on the ergodicity and randomicity of chaos parameter, mutation arithmetic operator withdifferent scale is formed in order to exploit the variable space, in the light of family eugenics and uniform design,orthogonal and uniform operator are constructed, at the same time the positive feedback mechanism is used tosimulate the information communion of individual during the local exploration, and thus a new and mixedevolutionary method is presented. The application of this evolutionary method on the search for the minimalsafety factor of the slope shows that it is valid.更多还原
