- The optimal model of truss structure is established , in which the cross sectional areas of bar are taken as design variables , the structure weight is taken as objective function . in the process , the reliability of structural displacement and bar stress and the fundamental frequency are taken as constraint functions . from the engineering practice , all the reliability constraints , which are implicit generally with the design variables , are equalized and transferred to the conventional explicit constraints
本文将主要考虑桁架结构的优化问题，首先建立数学模型，即以桁架的横截面积为设计变量、以重量最小为优化目标，位移、应力等可靠性及基频为约束条件；最后，从工程实际出发，对结构系统的可靠性隐形约束进行等价显化处理，使之转化为常规的横截面积优化问题。 - For problems whose objective function or constraint functions have sharp curves on their contour maps ( such as the rosenbrock ' s function which has banana shape contours ) , monotonicity may cause a series of very small steps , causing a huge number of iteration to reach their solutions . by using the nonmonotone technique , we get the sequence of successful interative point which should make the objective function mono - tonically decreasing . hence , we use both trust region strategy and line search technique and make each iterate generate an acceptable trial step in interior feasible set as next interative point
我们利用非单调技术得到使目标函数非单调下降的迭代点，因为非单调克服高度非线性化函数的求解问题，从而避免了只使用单调搜索在“峡谷”现象局部最优解被卡的情况，我们用信赖域策略和非单调线搜索技术相结合的方法，使算法产生的迭代步落在可行域内点，同时又在信赖域内满足接受准则。
