rank-based model meaning in English

排序选择模型

An optimizing method based on biological evolution - genetic algorithm is proposed to the problem of the construction process planning analysis . adapting the successful experience of path optimization problem , improved genetic operators are adopted : the sequence of numbers , which is arranged by the removal order of members , is assumed to represent a chromosome by natural code ; transforming baseline information of this problem into immune operators ; combining rank - based model with elitist model ; designing special crossover and mutation operators . the mathematical model for computer and special programs are provided in this paper
借鉴遗传算法在求解路径优化问题上的成功经验，应用了改进的遗传算子：采用自然数对结构去除构件进行编码，将所求问题的基本信息转换成免疫算子，采用稳态最优保存策略和排序选择方法相结合进行选择，采用适用于本问题研究的特殊的交叉算子和变异算子，从而来讨论在桁架结构施工路径优化问题中使用遗传算法的可能性。
