Example Sentences:

	1.	( 3 ) the span analysis of the genetic operators . 8 schemes were provided to analyze the relation of the genetic operators such as population size , cross probability , mutation probability . at last , a optimum group of genetic operators was selected 提出8种方案来分析遗传操作算子(种群规模、交叉概率和变异概率)之间的联系，并根据精度最高原则最终确定一组合适的遗传操作算子。
	2.	Qga combining the genetic algorithm and the quantum information theory has a large search space with small population and a good global search capability , while image sparse decomposition based on mp is an optimal problem , so it can be fast solved by qga 量子遗传算法能用较小的种群规模实现较大的空间搜索，全局寻优能力强，基于匹配追踪的图像稀疏分解是最优化问题，因此可用量子遗传算法快速实现。
	3.	Router congestion control strategies are also proposed . secondly , a new multicast routing algorithm based on double chromosomes genetic algorithm is realized . the simulation results show that this algorithm can get better convergent effect and select best routing under proper system parameters 然后重点介绍了本文提出的一种基于双倍体遗传算法的组播路由算法，仿真结果表明该算法能够在参数(种群规模、浙江工业大学硕士学位论文摘要交叉率及变异率)选择适当的情况下，取得较好的收敛效果，并可以确定最优路由。
	4.	In the genetic process of reproduction , crossover and mutation of the chromosomes in this method , these operators pr , pc and pm are produced randomly within some space , the scale of population and all kinds of genetic probability are also adjusted randomly so that the diversity individuals of population is ensured . the ga of dynamic population scale passes more information of paternal chromosomes to the offspring , which is beneficial to search the global optimization or quasi - global optimization 该方法在染色体进行繁殖、交叉、突变的遗传过程中，在某一范围内随机选取p _ r ， p _ c ， p _ m ，动态调整种群规模，保证了种群个体的多样性；选择同父本分别进行三种遗传过程使得父本染色体中有更多的信息传递给子代，这有利于搜索全域最优解或准最优解。
	5.	The coding of the variables that describe the problem is always large . in order to find the best optimal result , it needs the larger population and the longer course of optimization . that will spend much time and money , so the appropriate population size is a factor that affects the efficiency of genetic algorithm 在应用遗传算法时，初始种群的产生一般是随机的，它往往需要的编码长度很大，导致需要很大的种群规模或者很长的进化过程才能有较好的优化效果，这将耗费大量的计算时间和费用。
	6.	Abstract : biological invasions are a continuous feature of a non - equilibrium world , ever more so as a result of accidental and deliberate introductions by mankind . while many of these introductions are apparently harmless , others have significant consequences for organisms native to the invaded range , and entire communities may be affected . here we provide a survey of common models of range expansion , and outline the consequences these models have for patterns in genetic diversity and population structure . we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes , and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion . we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales . finally , we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera , cynipidae , cynipini ) in europe . we show that over timescales ranging from 500 10000 years , allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes , confirming the role of glacial refugia as centres of genetic diversity over these timescales , and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species . this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps , particularly host oak plants 文摘:生物入侵是不均衡世界的一个永恒话题,尤其是当人类有意或无意地引入物种后.很多引入显然是无害的,但另外一些则有着严重的后果,会给入侵地的生物以至于整个生物群落造成影响.本文总结了分布区扩张的常见模式,概述了它们对遗传多样性和种群结构式样所造成的影响.描述了如何根据以一批遗传标记所得到的遗传多样性式样来推断入侵途径,来揭示伴随扩张选择和漂变在形成种群遗传样式中的作用.本文对日益增多的群体遗传学方法进行了总结,这些技术可以用来在不同的时间尺度上推断种群规模所发生的巨大变化(瓶颈效应及种群扩张) .最后,我们以欧洲栎瘿蜂(膜翅目,瘿蜂科,瘿蜂族)一系列入侵的数据为例对一些方法进行了说明.从500 10000年的时间尺度上,多态的等位酶位点上等位基因频率的数据表明: 1 )遗传多样性沿入侵路线呈不断下降的趋势,支持了冰河期避难所作为遗传多样性中心的作用; 2 )入侵地区的种群与该物种原产地的种群相比,遗传上的分化更为强烈.这种种群结构在空间上的变异可能是被栎瘿蜂开发的资源尤其是栎树寄主在斑块上出现变异的反映
	7.	In consideration of the defects of conventional ga , an improved ga has been investigated in this paper . the evolution speed and quality of the population are directly influenced by the change of the number of chromosomes in ga and by whether the paternal excellent information is passed to the offspring as much as it can . in regard to the questions existing in ga , an algorithm with dynamic population scale is provided in this paper 在对模拟电荷配置的程序化实现方面，本文采用智能优化方法? ?遗传算法( ga ) ，不过本文针对传统ga - csm中遗传算法的定种群规模遗传使得父本染色体的多样性受到限制及同代非同父本进行繁殖、交叉、突变的遗传方法可能收敛于局部极小值而得不到全局最优解的问题，对其加以改进，提出了一种新方法? ?变种群规模的遗传算法。
