例句与用法
- Introduction of prepotency operator in the initialize population step and the improved mutation operator accelerate the convergence process , and the introduction of new operator in forming new population step avoid converging in local optimum , and promote the ability of global convergence
算法在初始化种群阶段引入了“优生”算子,以及改进的变异操作使算法的收敛速度大大提高;在形成新种群阶段引入新的算子避免了局部早熟,提高了全局收敛能力。 - At present , h9n2 subtype influenza viruses are prevalent in terrestrial poultry worldwide . what is more , the introduction of these new types of terrestrial poultry was in southern china , a hypothetical epicenter for the emergence of pandemic influenza viruses . it is , therefore , more important to carry out influenza surveillance , especially in those newly forming poultry in this region
目前h9n2亚型流感病毒分布广泛,多次发生传染人的事件,加上华南地区作为理论中“流感中心”的特殊地位,因此对该地区进行严密的流感病毒监测具有重要的意义,特别是对近年来该地区不断涌现的新种群中流感病毒进行检测。 - Here we report that the genetic identification of h9n2 influenza viruses from those newly forming poultry in this region , partridge and chukka . our results suggest that those h9n2 influenza viruses isolated from these types of terrestrial poultry are not sorted into the following two genotypes , i . e . , qa / hk / gl / 97 - like and dk / hk / y280 / 97 - like virus lineages . genetic analysis revealed that some of them are reassortment viruses between above two lineages
结果表明, h9n2亚型流感病毒在这些新种群中广泛流行,并且检测到多个基因型的存在,进化树分析证实有多个基因型与同期在水禽类中分离到的基因型相近:这表明h9n2亚型流感病毒很可能通过发生跨种属传递从水禽感染这些小种群陆基禽类。 - The main research work of dissertation can be concluded as follows : 1 . two kinds of hybrid strategies of genetic algorithms and tabu search are discussed systematically in this paper . the idea of tabu search is introduced to improve crossover operator and mutation operator of genetic algorithms for the first strategy , while tabu search is executed to a certain proportional selected individuals in the population after genetic evolution of every generation for the second strategy
本文的主要研究成果概括如下: 1 .论文比较系统地探讨了遗传算法和禁忌搜索算法的两种混合策略:第一种是利用禁忌搜索的思想来改进遗传算法的交叉算子和变异算子;第二种是对每代中交叉变异后得到的新种群中的一定比例的个体进行禁忌搜索处理。
