| 1. | The scientists found that the new versions of the two genes evolved much faster in apes than in mice and rats 科学家发现这两种基因的新版本在类人猿身上的进化速度远比在老鼠身上的进化速度快。 |
| 2. | They examined the number of mutations in the dna sequence of each species to estimate its rate of evolutionary change 他们检查了每个物种的dna脱氧核糖核酸序列中基因突变的数量,并以此估计出该物种的进化速度。 |
| 3. | In the improved ga , it is ensured that the optimized probability of every parameter is approximately equal and so the search is speeded to a great extent 这种算法保证了被优化参数参与优化过程的概率基本均等,较大幅度地提高了进化速度。 |
| 4. | People are evolving more rapidly than in the distant past , with residents of various continents becoming increasingly different from one another , researchers say 研究者称人类的进化速度远比过去要快,各个不同的大陆的居民彼此之间越来越不同。 |
| 5. | Knowing when the two split has implication both for understanding how quickly evolution works and for imagining the likelihood of intelligent beings elsewhere in the universe , researchers said today 研究人员于今日宣布,了解两者间何时分化既会增加我们对生物进化速度的了解,同时对宇宙中其他地方存在智慧生物的设想也有重要意义。 |
| 6. | Evolution for 1000000 years process is hit by human being in several , except cerebrum ' s evolution speed happens change body ' s inherent latent energy and the motion cell of organization are proceeded orderly other than , degenerating 人类在几百万年的进化过程中,除了大脑的进化速度发生改变以外,身体的内在潜能和运动组织细胞被逐步退化。 |
| 7. | Mitochondrial dna has been used in researches on heredity structure of animal strain and strain identification in the past few years . chinese mitten - handed crabs from yangtze , liaohe and oujiang rivers were studied in our research 线粒体dna以其结构简单、进化速度快、无组织特异性等特点已被较多的运用到动物种群遗传结构分析及品种鉴定的研究。 |
| 8. | Taking itae criterion as evaluating function of hydro - generator fuzzy gpss , the head - and - tail alternate crossover ga is compared to classical ga . the results show that the evolutionary rate of the former is apparently higher than the latter under a same accuracy 以itae指标作为设计水电机组模糊gpss的评价函数,对首尾轮换交叉遗传算法与常规交叉遗传算法进行比较,结郑州大学工学硕士论文果表明,对同样的参数精度,前者的进化速度明显高于后者。 |
| 9. | Abstract : simulated annealing and multigroup parallel evolution are two helpful methods which can improve the performance of genetic algorithm . these two ideas are well combined in this paper , and a new algorithm is derived , that is the multigroup parallel genetic algorithm based on simulated annealing method . simulation results show that this method not only quickens the computation , but also improves the convergence efficiency , thus produces more satisfactory results 文摘:模拟退火和多种群并行遗传进化是两种较好的改进遗传算法性能的方法.将这两种思想有机地结合起来,提出了一种基于模拟退火机制的多种群并行遗传算法.仿真结果表明,该算法不仅能增强算法的全局收敛性,还能加快遗传进化速度,得到满意的全局最优值 |
