查询词典 decrease in population

In the solution process the initialization two populations, separately will select the different overlapping variation probability, after each time will iterate the sufficiency high individual carries on the first populations in sufficiency low individual with the second population in the exchange, and will preserve each center group the optimal solution to the outstanding person population, by will solve the tradition genetic algorithms to be easy to appear precociously, will be easy to fall into the partial optimal solution question.

即在求解过程中将初始化两个种群，分别选取不同的交叉变异概率，在每一次迭代完后将第一个种群之中的适应度较低的个体与第二个种群中适应度较高的个体进行交换，并且保存每个种群的最优解到精英种群，以解决传统遗传算法容易出现早熟，容易陷入局部最优解的问题。

To take advantage of the chaotic mapping, a repetition prepotency evolution algorithm with a population initialized by chaotic numbers is developed in which the chaotic mapping is an uncommon seeding-machine to produce different initial'chromosome'populations never appeared before for PE algorithm. The combination of chaotic mapping and PE makes PECA be able to probe lots of optima rapidly and effectively owing to the quick convergence speed of PE and relatively high population diversity guaranteed by chaotic mapping.

结合混沌来初始化优势进化算法的群体成员，还设计了基于混沌初始化群体成员的循环优势进化方法，该方法在混沌保证每次优势进化绝对不同的初始群体成员的情况下，不仅具有了优势进化的快速收敛优点而且有混沌映射保证群体成员的高度多样性，从而可以快速探测很多局部最优点，大大提高了找到全局最优点的机会，用它训练神经网络预测四卤化物振动频率研究充分体现了该策略的优越性。

Key factors to be considered, in addition to differences in economic conditions and affluence, include:* The National State—its centralization and population diversity * Reliance on Market Processes—acceptance of public regulation of economic activity * Conceptions of Property and Ownership Rights—extent of public land ownership * Environmental Risk Perceptions and Tolerances—experience with man-made disasters * Systems of Land Use Controls—quality of record-keeping and public disclosure of land conditions * Public Policy Decision-Making Processes—and the extent of neighbourhood influence over decisions * Extent of 'Economic Development'—coverage of basic needs, and population migration patterns

除了经济条件和富裕情况的不同，需考虑的主要因素包括：(1)国家的状况——中央集权和人口的多样性；(2)对市场的依赖——对经济活动的公共规则的接受；(3)财产和所有权的概念——公共土地所有权的程度；(4)对环境风险的感知和承受力——人为灾难的经验；(5)土地使用控制系统——档案记录的质量和土地信息的公开；(6)公共政策的决策过程——以及邻里之间对决策的影响程度；(7)"经济发展"的程度——满足基本需求的程度和人口的迁移模式。

Some important traits, i.e., oil and protein contents, 100-seed weight, and the resistance of soybean to Bean pyralid in F2 population, the resistance of soybean to soybean mosaic virus with strain Sa in the F2:3 population, and the number of branches, the number of main-stem nodes and plant height in the F2 and F2:3 populations, were measured.

主要结果如下： 1。连锁图总长度为1091.34cM，标记间平均距离为16.53cM。利用公共遗传图谱，将21个连锁群与大豆染色体相对应。每个连锁群上的标记数目在2-8个之间，连锁群长度在17.71-129.33cM之间。相邻标记间平均间距最大的连锁群为D1b，为43.55cM；最小平均间距的连锁群为M，为13.86cM；有20个区间长度大于20cM。

This study showed that population in Chiayi City didn't have enough recognition to the hazard effect of betel quids; hence, the oral health education should be promoted. Besides, we can screen the high-risk population and find the reasons for which they abused and failed to stop chewing. Furthermore, one can develop effective program for cessation of betel quid chewing and smoking.
