遗传算法的运行机理及特点是具有定向制导的随机搜索技术，其定向制导的原则是：导向以高适应度模式为祖先的“家族”方向．以此结论为基础．利用随机化均匀设计的理论和方法，对遗传算法中的交叉操作进行了重新设计，给出了一个新的GA算法，称之为随机化均匀设计遗传算法．-Operating mechanism and genetic algorithm is characterized by directional guided random search techniques, the directional guidance of the principle is: the fitness-oriented model of high ancestral " family"　orientation. The basis of this conclusion. By randomized uniform design theory and method, the crossover operation in genetic algorithm has been redesigned, GA gives a new algorithm, called the randomized uniform design of genetic algorithms.
