有效限制

A new and efficient learning algorithm of asociative memory neural network is proposed, with the following characteristics:(1)it can store any given training pattern set no matter how much and what correlation among them may be;(2)the smallest domain of attraction of training patterns is maximized;(3)each domain of attraction of training patterns is guaranteed to be as large as possible;(4)the designed associative memory network is globally stable.

摘要提出一种新的联想记忆网络模型的有效学习算法，它具有下述特点：(1)可以全部存储任意给定的训练模式集，即对于训练模式的数目和它们之间相关性的强弱没有限制；(2)最小的训练模型吸引域达到最大；(3)在(2)的基础上，每个训练模式具有尽可能大的吸引域；(4)联想记忆神经网络是全局稳定的。

In fact, experience and experiment are used dominantly. But the empirical method is not always reliable because of its limited available range.

经验规律的可靠性受多方面因素的影响，有效适用范围常受较大限制。

Dux, a former research fellow at Vanderbilt, and now a faculty member at the University of Queensland in Brisbane, Australia, and co-author of the study, said.

Dux，这位范德堡大学的前研究员，澳大利亚布里斯班昆士兰大学的教职员同时也称：我们发现了在有效进行多任务操作方面的一个关键限制点，它可以控制我们的脑额叶前部皮层中正在处理的信息，这样通过训练和练习可以极大地增加速度。

In order to make available for alternative Aiming bidding curves,improve the speed,precision and convergence, an effective method for generation scheduling is proposed based on an improved dynamic programming- local redefined dynamic programming .

Secondly, The introduction of feoff system resulted in the partition of the public power of England, feoff system became the extreme obstacle in making a centralized kingdom of England ; The formation of the common law built up an supreme authority for the law.

其次，封君封臣制及庄园制的引入导致王国公共权力的分散，是中央集权的最大障碍；普通法的形成则树立了法律至上的权威，构成了对王权长期而有效的限制。

Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。

For any RLC electric network given, the software can found its state equation over the field F of the rational functions in multi-parameters very swiftly and effectively, and can analyze its controllability automatically. Moreover there is not any additive restriction for its complexity.

对任意给定的RLC电网络均能十分快捷有效地生成其在F上的状态方程，并能对其能控性进行自动分析判别，而对其复杂程度没有任何附加限制。
