( 2 ) aiming at the discrete structure of composite shells , this thesis proposes two integer coding method , then uses one of them to optimize composite shells ( 2 )针对复合材料层合壳的离散型优化特点,提出两种整数型编码方式来表征层合壳结构参数。
We compare the algorithms in the present work with the traditional algorithms , and can come to the conclusion that the former is more efficient . in the work we discuss the point - by - point algorithms of implicit curve and surface systematically , introduce the general and extended algorithms of line - drawing , and have these algoritms improved . an all - integer arithmetic algorithm is also introduced , we improve the algorithm and extend it to surface 介绍了隐式曲线的整数型逐点生成算法,将它进行改进,扩大了它的适用范围;并将这个算法推广到隐式曲面,把隐式曲面的绘制问题转化为隐式曲线的绘制问题,提出了一个对隐式曲面有效的逐点生成算法。
