摘要
最优化计算方法的研究虽然发展很快,但对于工程设计中遇到的典型的多维非线性约束最优化问题,却缺乏一些设计工作者所期望的简便有效的方法,因对这些问题,人们一般难于利用其解析性质.现有的几种直接法均存在收敛慢的问题,将其运用于高维的情况则变得十分无效,针对上述情况国,作者提出了“严格单纯形”法,用以求解一个建筑群的优化数学模型获得了成功.
The research on the computational method of optimization develops fast, but a convenient and efficient method which engineers need very much is lack for some practical optimum problem with higher dimension, beingnon-linear and subject to non-linear constraints. The main reason is that onecan hardly utilize its analitic characteristics. A few direct methods being used have a problem of converging slowly and would be very inefficient. So, the authors of this paper brought up a method of 'strict simplex' and successed to solve a complex optimum model of a structure group.
