多层复形法在结构优化中的程序设计

Programming of multilayer complex method in structure optimization

对结构优化设计中使用得较多的复形法进行了扼要介绍，比较了普通复形法与多层复形法的优劣，并设计了两种方法的具体算法。算例证明，多层复形法减少了调优搜索迭代次数，增加了程序的稳定性。

Compendious introduction of complex method frequently used in optimal design of structures and comparison of multilayer complex method (MCM) with ordinary complex method (CM) are made in this paper. Algorithms of both methods are designed. The results of the example prove that MCM has the advantages over CM in iterative times and stabilityof program.
