离散型规划

Based on the relationship between matrix and symmetric matrix global exponential stability of the discrete-time neural networks model and the result of exponential convergence rate were obtained by using the characteristics of eigenvalues of a positive definite matrix and introducing a proper factor.

针对带有边界约束的凸二次规划问题，利用离散神经网络模型的建模原理，构造了一个神经网络模型。利用矩阵与对称矩阵的关系和正定矩阵特征值的性质，通过引入一个适当的因子，得到了该离散型神经网络模型是全局指数稳定性和指数收敛率的结果。同时分析了该结果的优越性和存在的不足，提出了解决的3种方法，最后给出了实例说明本方法取得结果的实用性

In chapter 7, quality loss cost is first used in the model of simultaneous design of tolerance, and economically attainable accuracy of position is first considered as constraint condition. It is first proven that the function of simultaneous design of tolerance is non-convex program; discrete and continuos Simulated Annealing are introduced; the optimum software to solve this model is given.

第七章首次将质量损失成本用于公差并行设计的优化数学模型中，并首次考虑位置精度的经济加工精度范围作为约束条件；论证了公差并行设计优化模型的非凸规划问题；着重介绍了离散型和连续型的模拟退火算法SA；研制了公差并行设计的优化软件。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
