| 摘 要： | 在很多全局优化问题中，尽管目标函数和限制条件通常为非线性的，但仍会遇到某些参数和某些目标之间存在一些已知的单调关系．本文研究了在全局优化中利用参数和目标的关系以得到搜索点的不可行方向，由此可有效的引导优化算法在有希望的空间中开发，并加速演化进程．在目标评价为时间消耗型的情形如半导体器件综合时非常适用。

| Abstract: | In many global optimization problems, there exist some monotonous relations between parameters and some objectives, although the objective and constrain condition functions are nonlinear. The principle of incorporating relations between parameters and objectives to finding the infeasible directions of searched points in global optimization is studied. It can guide optimization algorithms exploiting in promising space and accelerate the evolutionary process. It is very suitable for the case of that the evaluation for objectives is time consumption, such as semiconductor device synthesis. |
