分类总结工程离散变量优化设计方法。采用现代离散变量的优化设计方法 ,不仅可以使优化设计结果所提供的数据完全符合设计规范的要求 ,而且由于只在有限的离散点上进行计算 ,从而可大大加快优化计算的速度 Classification of engineering discrete variables optimization design method. The optimization design method using modern discrete variables not only can make the data provided by the optimal design result fully comply with the requirements of the design specification, but also can speed up the optimization calculation greatly by calculating only on a limited number of discrete points
