更新函数

According to the Lyapunov stability theory, the weight update law of neural network, the adaptive law of error bound, the stabilizing function and the control are obtained, thus the stability of closed-loop control system is ensured.

基于Lyapunov稳定性理论，得到了神经网络的权值更新律、误差界自适应律、稳定函数及控制律，确保了闭环控制系统的稳定性。

Extremal optimization algorithm is a new heuristic method, whose principle is to select and update the worst variable, and improve the fitness of the whole problem.

极值优化算法是新开发的一种启发式算法，其基本思想是更新适值最差的变量，提高目标函数的适值。

Secondly, for the same hash function, the sample with the minimum hash value is selected as the global sample and the local samples are combined at the center node to filter out the biased effect of duplicated updates.

然后，对于相同散列函数产生的样本选取具有最小散列值的样本作为全局样本，完成局部样本集在中心节点的合并，滤除在分布节点上的重复更新对样本偏斜的影响。

If a functor needs to update some state variables, which is often the case, it is better to use references to external data.

如果一个仿函数需要更新某些状态变量，这是很常见的，最好还是引用外部数据。

Gauss- Seidel iteration method is to function in the calculation of the first equation obtained after the first argument, it updates the independent variables into the second equation.

详细说明：高斯-赛德尔迭代计算方法是在计算第一个方程函数得到第一个自变量后，吧自变量更新进入第二个方程计算。

We prove that the GerberShiu functionΦsatisfies a renewal equation and a infinite series expression ofΦis obtained.

在本章中，利用逼近的方法，得到了此风险过程的罚金折现函数Φ满足的更新方程及其Φ的一个级数表达式。

Many methods for mapping XML to relations have been proposed without considering the semantics of XML data before. But the semantics is very important to design schemas for storage, optimize queries, and check update anomalies, etc. In the presence of XML FDs which are specified over DTDs, this paper presents a method based on the hybrid inlining to map XML to relations for storage.

有许多文章提出了根据DTD将XML映射成关系的方法，但都没有考虑XML的语义，而语义信息对数据存储模式设计、查询优化、更新异常检查等来说是十分重要的，如果在DTD上指定了XML的函数依赖，在映射到关系数据库中就需要将其考虑进去。

A new variable step-size LMS adaptive filtering algorithm is presented, which makes use of the intercorrelation function of the relative output error signal to control the new variable step-size.

针对上述问题，提出了一种新的变步长LMS自适应滤波算法，它采用相对的误差互相关函数来控制步长更新。

The Green′s function is updated in every iteration step.

在每次迭代过程中，格林函数不断被更新。

Following are the main results of this thesis: Detailedly analyze some related schemes concerning group key management, We reconstruct a tree key management scheme, in comparison with Logical Key Hierarchy and One-way Function Tree schemes, we find that it has good performance of key storage, re-key communication costs and calculation of group manager.

本论文的主要研究成果如下：对目前存在的多播组密钥管理方案进行了详细的研究分析，提出了一种改进的树型管理方案，与逻辑密钥分层方案和单向函数树方案进行分析比较，它在密钥存储、密钥更新、通信量以及组管理者的计算量方面均有较好的性能。
