selection by mutation

Thirdly, the algorithm for realizing immune memory is designed by applying the affinity mutation algorithm and negative selection algorithm. This algorithm can get more efficient memory detectors and delete those memory detectors which may make error report in time.

引入亲和力成熟算法和阴性选择算法，改进实现免疫记忆的算法，该算法能得到更有效的记忆检测器，并及时去除可能会产生误报的记忆检测器；

Selection and RAPD Identification of Excellent Auricularia Auricula Strains by Ultraviolet Mutation

紫外线诱变筛选黑木耳优良菌株及RAPD鉴定

The splicing/ decomposible encoding scheme proposed by Xu et al is applied to the construction of dynamic selection and mutation operators that were built respectively on the levels of genotype and phonotype of population. A completely new adaptive genetic algorithm is thus developed.

基于新的编码与判据，分别在种群层次与基因层次发展了动态变异与动态选择操作，进而提出了一类自适应遗传算法。

It is important to decide how to rejuvenate reduced mutation accumulation of stored seed, and counteracted the genetic changes by drift, fitness selection and contamination with alien pollen or seed that may occur during regeneration.

降低贮藏种子基因突变的累积效应，控制种质资源繁殖更新过程中由于遗传漂变、选择和污染所引起的遗传改变，对制定科学的种质资源繁殖更新策略十分重要。
