BACKGROUND&AIM: To investigate the mutation frequency and molecular mutation of spontaneous mutations on the tk gene of mouse lymphoma cells.
7c-tk+/-细胞tk基因的自发突变频率和分子突变。
To improve the veracity of forecasting,a hybrid GEP algorithm was presented,which combined GEP based on mutation operator and evolutionary algorithm based on colony-search strategy.
为了提高预测的准确性,结合基于突变算子的基因表达式和一种基于群体搜索技术的演化算法,提出了改进的GEP方法,并用其对数据进行演化建模。
The key to this algorithm lies in the construction of a new mutation operator controlled by a stable factor,, which maintains the polymorphism in the colony by setting a stable factor and changing certain best seeds to mutant.
该算法的核心在于,稳定参数控制下的突变算子的构造,通过稳定参数的设定来稳定种群中最优个体的数目,并有目标地对最优个体进行突变操作,以达到快速扩大搜索空间、稳定群体中个体多样性的目的。
