The improved ga not only increases the ability of local search through the local search operator , but also breaks the monopoly predominance of the genes , and increases the diversity of population 不仅通过局部搜索算于增强了遗传算法的局部搜索能力，还能打破旧有基因的垄断优势，增加基因的多样性，创造有生命力的新个体。
The sustainable vitality shall ever lie in culture development for a country with such abundant tradition and history . “ yushan dongxi ” is developed from this standing by integrating ecology , cultural context , and geographical background to a supplier of products and service 而真正有生命力的商业是有主题的商业，以文化为主题的商业更是古老中华民族及悠古三秦民俗的出路。
The dissertation mainly aims at applying several active machine learning strategies to intrusion detection and systematically studies signal analysis techniques of intrusion detection based on statistical learning theory ( slt ) , symbol inductive learning theory and genetic learning method . meanwhile , performance comparison and evaluation among intrusion detection techniques based on different machine learning strategies are presented according to computational learning theory and statistical hypothesis test methodology . intrusion detection is regarded as a pattern recognition problem in term of statistical learning theory ; i 本文的主要工作是将目前几种有生命力的机器学习策略应用于入侵检测技术中,论文从入侵检测的不同视角出发,系统深入地研究了统计学习理论、基于符号的归纳学习理论和遗传学习方法在入侵检测信号分析中的应用技术,并在可能近似正确( pac )学习框架下,利用计算学习理论和统计假设检验方法对基于不同机器学习策略的入侵检测方法进行了性能比较和评估。
Chapter ii discusses the social and historical background under which information brokering bloomed and developed , with an attempt to illustrate its originating and developing social circumstances as being a new - born energetic industry , in addition to the phases and forms in the process . meanwhile , it discusses the effect on its own future development 第二章主要讨论信息经纪业在国内外兴起的社会历史背景及其所经历的历史过程，旨在说明信息经纪业作为一个新的有生命力的行业产生和发展的社会环境，以及在此过程中经历的阶段和形态。
There undoubtedly exists a connection between all the people living at one time , and so it is possible to find some sort of connection between the intellectual activity of men and their historical movements , just as one may find a connection between the movements of humanity and commerce , handicrafts , gardening , and anything you like 毫无疑问，同时存在的有生命力的事物之间都存在着联系，因此从人们的智力活动和他们的历史运动之间也可以找到某种联系，这就像在人类的活动和商业手工业园艺，或者任何哪一行业之间可以找到这种联系一样。
After had been being debugged and improved several times , dfmis - 1 system bad been run formally . the benefit resulting from running of this system proves that the research way is correction , the method of realizing system function is feasible and the system has life force . the dfmis - 1 system has laid the foundation of extending entirely works for becoming information enterprise Dfmis - 1系统通过多次调试和改进，已在公司的现场投入实际运行，并取得了一定的效益，从而证明了本课题的研究方向和思路是正确的、办法是可行的，系统是有生命力的，为公司今后全面铺开信息化工作奠定了基础。
