| 摘 要： | :提出了基于精度的变步长优化方法 ,并给出了基于精度要求的变步长和基于排序的一维搜索两个新概念 .该方法使优化设计与各个设计变量的精度要求紧密结合在一起 .另外 ,还提出了对于多峰一维搜索问题 ,只有当所求函数的凹凸性与确定一维搜索区问题的步长以及求解最优步长因子的方法匹配时 ,才能用一般方法得到搜索区间内的最优解 |
| 关 键 词： | 精度要求 变步长 优化设计 |

| Abstract: | An optimizat ion method of variant step length based on precision and two new concepts "vari ant step length based on precision" and "one-dimensional search based on the sorting" are presented.They make the optimum design closely combined with preci sion of every design variable.In addition,the authors propose that for a multi- peaked one-dimensional search problem its optimum solution can be obtained by o rdinary optimization methods only when the convexity or concavity of the objecti ve function matches the step length determining the one-dimensional search regi on and the method of finding the optimum step length factor. |
| Keywords: | required precision variant step length optimum design |
