| 1. | According to the distinguished result , the algorithm adaptively sets the mutation rate
根据辨识结果，自适应地设置变异概率。 |
| 2. | Low mutation rates cause the population to reach high fitness as a whole much slower
变异率低导致了需要更多的时间人群才能整体上达到高适应性。 |
| 3. | In order to speed up the convergence , the crossover and mutation rates are adjusted with on - line fuzzy control according to the evolution situation
为加快收敛速度，根据种群进化情况对交叉率和变异率进行在线模糊控制。 |
| 4. | The mutation rate of the virus was most rapid during the early part of the epidemic between the time of the first emergence of sars to the first major outbreak in guangdong province
不断在人体内变异以适应人体病毒在sars疫症初期（即出现第一病例至广东省大爆发）变异速度最快。 |
| 5. | Computational results reveal that the hybrid genetic algorithm can efficiently solve the considered problem and the reduction of makespan is related to the mutation rates and the number of generations
结果显示，混合式基因演算法可有效的求解测试问题，最大完工时间的降低和突变机率与世代数相关。 |
| 6. | 1 ) a conclusion is made that there is an optimal combination of crossover rate and mutation rate after study on the relationship of that two rates . thus the blindness of selection of the two rates is reduced in a way
1 )对交叉率与变异率的关系进行研究，得出两者存在最优组合关系的结论，在一定程度上减少交叉率与变异率选取的盲目性。 |
| 7. | The performance of the proposed hybrid genetic algorithm is evaluated by two real - world problems and the solution quality of the proposed approach is analyzed under five levels of mutation rates and four levels of number of generations
此混合式基因演算法的绩效将透过两个实务的问题的求解加以测试，并且根据五种突变机率与四种世代数进行分析。 |
| 8. | The analysis revealed that the sars - coronavirus was mutating continuously throughout the epidemic . the estimated mutation rate of the virus , however , is one - third that of the virus responsible for the acquired immunodeficiency syndrome ( aids )
分析结果显示sars冠状病毒虽然演变迅速，但sars冠状病毒基因组的中性突变率只是爱滋病毒基因组的突变率的三分之一。 |
| 9. | Now next step we have to think about the ten years treatment , ten years mutation rate is 10 percent , then 90 % percent can use a drug for 10 years , then you might change the so - called natural cause of diseases
但是我们要考虑的是10年长期的服药，如果10年的变异率是10 % ，仍然在这10年里面，我们90 %的药物疗效是用来抑制病毒复制，而且效果好，可以延缓俗称的自然肝病病程进展。 |
| 10. | This dissertation uses genetic algorithm to choose optimum parameters for the widely used pid controllers . in the optimization calculation process , mutation rate , cross rate and parameter range are adaptively changed to accelerate optimization process
本文用遗传算法优化工程中广泛使用的pid控制器的参数，采用变参数区间、变交叉变异概率等方法提高计算速度，并对适应值函数进行了改进。 |
