- Change tracking population requires an initial population of the full-text in question. 更改跟踪填充要求对相应的全文进行了初步填充。
- In PGA, genetic operation is simpler and the initial population need not to be varied and there is not immature convergence. 它具有遗传操作简单 ,不要求初始群体的广泛多样性 ,不存在“早熟收敛”现象等特点 ,非常适合于求解组合优化问题。
- DEGA searches all over the solution space as far as possible by lowering the affinities among the individuals of the initial population. 首先降低初始群体中各个体之间的亲和度,使得搜索尽可能遍历整个解空间。
- It also designs specialized genetic operator based on improved GA performance and adopts new initial population selection method. 同时从改进遗传算法性能的角度出发，设计了专门的遗传算子，并采用了新的初始种群选择方法。
- Observations on population dynamics of M.incognita showed that the multiplication rate decreased as the initial population density increased. 对南方根结线虫在烟草上的种群动态分析表明：随着线虫初始密度的增加，线虫繁殖率下降，二者呈指数关系。
- The multi-start 2-nearest neighbor searcher is presented for the construction of the initial population and a new adaptive heuristic mutation is adopted. 提出了多起点2-最近点搜索算法进行初始种群的构造,采用了一种新的自适应启发式变异方法,显著改善了原有遗传算法的搜索能力。
- Self-adjusting crossover and mutation rate are used and the initial population and population size are determined based on space division in this algorism. 为此，本文提出一种基于空间分割的遗传算法及初始种群产生和种群数量确定方法，并根据有关文献，提出一种自适应交叉、变异率方法。
- After the initial population and at least one incremental population are complete, enable the use of the index so that users can begin conducting full-text searches against the index. 在完成初始填充和至少一次增量填充之后,启用索引以便用户可以开始利用索引进行全文搜索。
