  individuals ' evolution
     To overcome one disadvantage of genetic algorithms that there is no explicit element to guid individuals' evolution, we propose a knowledge-model-based genetic algorithm in this paper.

A great number or historical racts snow that man's mnuence to ecosystem has become stronger and stronger and has gradully held on a certain special niche. According to the ideas of "progressive centralization" and "progressive mechanization" in L.v. Bertalan ffy's General System Theory, by reasoning the evolutionaiy process of cell and indivi dual from analogy, man's niche in ecoystem is deduced: it is not only the linkage of food chain, but also the regular-controller in ecosystem. On the basis of classical ecology, fully considering man's niche, a four-unitary structure of ecosystem including producer, consumer, decomposer and regular-controller is put forward. Further analysis shows that the appearance of mankind is the necessary historic product in the evolutionary process of ecosystem; social-economic-natural ecosystem is a two levels structured system with man kind as a contre and has a complex mechanism.

大量的历史事实表明,人对生态系统的影响越来越强,逐渐占据了某个特殊的生态位。本文运用L.v.Bertalanffy一般系统论中“趋中心化”、“渐进机构化”思想,通过与细胞、个体进化过程的类比分析推理,演绎出人在生态系统中的生态位:它不仅仅是食物链上的一个环节,也是生态系统中的调控者。并在传统生态学的基础上,充分考虑人的特殊生态位,提出生态系统的四元结构:生产者、消费者、分解者和调控者。分析表明,人类的出现是生态系统演化过程中的历史必然产物;社会-经济-自然复合生态系统具有以人为中枢的双层结构的系统复合机制。

Directional evolution operator is used to improve the conventional genetic algorithms.Considerations are given to the offspring by individuals both in the parent and current generations.The improved genetic algorithm is applied to a two dimensional multimodal function and a centrifugal compressor diffuser blade inverse design. Performance convergence is greatly enhanced.

为了有效找到全局最优,将“进化方向”引入到遗传算法中被认为是非常有用的.文中提出了一个新的进化方向算子,用于对标准遗传算法进行改进.该算子依据父代个体和当代个体的进化方向产生子代个体.进化方向的求取无须计算梯度.算子的作用对象是个体中的变量而不是染色体中的基因,因而适合于采用任何形式编码的遣传算法场合.包含该方向进化算子的遗传算法被用于二维多峰函数的极大值搜索问题,进行了对比验证.将新算法进一步应用于离心压缩机扩压器叶片逆命题设计问题,数值结果显示,改进遗传算法比标准遗传算法有好得多的收敛特性
