搜索

The two Armijo-type line searches proposed in Chapter 4 are shown to guarantee the global convergence of the class of conjugate gradient methods.

在第四章提出的两种Armijo型线搜索下，针对不同的线搜索参数分别讨论了共轭梯度法簇的全局收敛性。

Mathematical model has been dealt with by punish function search method. Hooke-Jeeves modular vector search method and Powell conjugate direction search method have been adopted and modified.

利用"惩罚函数"法进行了数学模型的处理，采用并改进了Hooke-Jeeves的模矢搜索法及Powell的共轭方向法，还提出一种随机搜索法。

It has been deduced that the search direction remains the same but that the step length decreases in optimizing the improved cost function with the conjugate gradient algorithm from the gradient of the cost function that the FIR filter apporaches the contrary point spread function more, and that the estimated image is closer to the original one.

从代价函数的梯度入手推导出共轭梯度算法，其搜索方向保持不变而搜索步长变小，使滤波系数更加逼近于点扩展函数逆算子，从而使估计图像与原始图像更加接近。

Mixed Discrete Random Programming is one kind of random arithmetic,this arithmetic's superiority is easy and quick, but it is easy to constringe partially.

离散变量随机搜索法属于随机试验法，算法具有简单、搜索速度快的优点，但容易造成局部收敛。

Among them 3 kinds of pattern are more familiar, it is mode of forum public relations, the small number of people gives out gigantic voice through occupying the platform such as forum, BBS by force, flooded popular true sound; 2 it is the network shoves a hand, prove through plan and lack but the operation with apparent directivity, the purpose; that achieves attack competitor or information to distribute searchs engine the 3rd kind namely, the search engine that holds market dominant position often screen inimical or the website that does not pay, put the content that with oneself interest positive closes in search result front row, one when intervene the practice that searchs a result made industry goes regular.

其中三种模式比较常见，一是论坛公关模式，少数人通过霸占论坛、BBS等平台发出巨大的声音，淹没了大众的真正声音；二是网络推手，通过策划以及缺乏论证但是指向性明显的操作，达到攻击竞争对手或信息散布的目的；第三种就是搜索引擎，占据市场优势的搜索引擎往往屏蔽不友善或不付钱的网站，并将与自己利益正相关的内容放在搜索结果前列，干预搜索结果的做法成为了业界的一条潜规则。

And if you need documentation, the Research Assistant provides context-sensitive documentation while the Xcode documentation window lets you browse and search for information.

并且如果你需要文档，Xcode的搜索助手提供了上下文敏感的文件，同时您可以在帮助文档的窗口中浏览和搜索信息。

Furthermore, the first-order optimality condition and its equivalent reformulations for generalized semi-infinite max-min programming with a non-compact set are presented using the lower-Hadamard directional derivative and subdifferential.2. Chapter 3 studies the gradient-type methods for unconstrained optimization problems. Section 1 proposes a new class of three-term memory gradient methods. The global convergence property of the method is established. Furthermore, in order to improve the convergence property of the method, a new class of memory gradient projection methods is presented with the property that the whole sequence of iterates converges to a solution to the problem under the conditions such as pseudo-convexity and continuous differentiability of objective function. In section 2, two new classes of methods, called gradient-type method with perturbations and hybrid projection method with perturbations, are proposed. In these methods, non-monotone line search technique is employed, which makes them easily executed in computer.

第3章研究了无约束优化问题的梯度型算法，第1节提出了一类新的三项记忆梯度算法，讨论了算法的全局收敛性，进一步提出了一类新的具有更好收敛性质的记忆梯度投影算法，并证明了该算法在函数伪凸的情况下具有整体收敛性，第2节在非单调步长搜索下提出了带扰动项的梯度型算法及其混合投影算法，这两类算法的一个重要特征就是步长采用线搜索确定而不象许多文献中那样要求步长趋于零，这样更容易在计算机上实现，在较弱的条件下证明了这些算法的全局收敛性，数值算例表明了算法的有效性。

An improved contour line extraction algorithm based on grid sequence is presented in this paper.

在网格序列法的基础上提出了一种改进的轮廓线提取算法———基于区域增长的轮廓线提取算法，该算法采用区域增长的方法来加速搜索边界单元，从而避免了搜索所有的网格单元。

Based on the theory, a new approach for convex quadratic programming with equality constrains is studied.

第三章介绍了拟牛顿算法，并给出了Armijo型线性搜索和Wolf-Powell型线性搜索。

In the meantime, have a search to announce shopping platform of network of the as biggest as the China that gives priority to with 3C B2C formally still -- 360buy Beijing east the store reachs cooperative agreement, indicate move shopping search entered brand-new development phase.

同时，有道搜索还正式宣布与以3C为主的中国最大B2C网络购物平台——360buy京东商城达成合作协议，标志着购物搜索进入了全新的发展阶段。

You need to lie low for a while.

你们得歇手一段时间

If you do, you may just be pleasantly surprised.

如果你开口问了，或许有意想不到的惊喜。
