约束

Linear memoryless state-feedback control law is derived for two classes of uncertain nonlinear interconnection systems with sector restriction or norm-bounded restriction based on Linear Matrix Inequality. This method doesn't require that two input terms are absolutely controllable for nonlinear delay systems.

the classic inventory model is optimizing model of nonrestraint. but in fact, it is usually restricted by funds, warehouse's space, service rate etc. therefore, many inventory models of variable restriction are produced in succession.

经典的存贮模型是无约束优化模型，但在实际使用时，却往往受到资金、库容、服务率等条件的限制，因此，陆续产生了带有各种约束的存贮模型。

该方法主要利用了正交特性，给出了一个针对正交空时分组码MIMO系统模型的无约束代价函数，并分析了该函数的全局最小值：该无约束代价函数的最小值实际上就是实际信道的归一化矢量。

According to the constraint condition request, modified Hungarian law is reaches basically the goal only by one step, at the same time, provide the all null elements which each line and each row need.,then check whether satisfy the constraint condition, otherwise must further make the zero.

匈牙利法的改进是根据约束条件的要求，基本上是一步到位造出每行及每列所需的零元素。然后检验是否满足约束条件，满足则可得最优解，否则需进一步造零。

Series of numerical examples are tested and the results are compared with that of some other algorithms.

The question of searching characteristic points or straight lines on moving rigid body is decomposed into two relatively independent sub-questions. The first one is to evaluate the characteristic of points and straight lines on moving rigid body, whose mathematics model is a kind of special non-differential max-mini optimal problem with inequality constraints. By the method of Saddle-point Programming and maximum entropy, the problem can be transformed as a differential optimal problem with single objective. The second oner is to search approximative character points or straight lines on moving rigid body within design space, whose mathematic model is nonlinear and non-differential problem with multiple constraints.

本文将在运动刚体上寻找特征点或直线的优化问题分解为两个相对独立的子问题，一是对运动刚体上点或直线的特征性评定，其实质是平面曲线的圆度或直线度的评定问题，优化模型是以最大误差为最小作为优化目标的约束不可微的优化问题，本文采用鞍点规划和极大熵方法，将其转化为单目标可微优化模型；二是在设计空间内，寻找运动刚体上特征性评定指标最小的近似特征点或直线，其优化模型是非线性、多约束的不可微优化问题，本文提出用遗传算法和BFGS局部搜索法相结合来求解。
