记载每一代的进化过程中保留多个最优个体不参加交叉，变异等遗传运算，而直接将他们复制到下一代群体中。-Documented the evolution of each generation to keep more than the best individual does not participate in crossover and mutation genetic operators, and direct them to the next generation of copy group

The scr ipt fits a given general analytical law using Genetic Algorithms. Such law can depend on several input variables and various parameters, but it must have only one output, to be matched to the input variable y. The optimum coefficients a

The paper presents an in situ parameter estimation method to determine the equivalent circuit parameters of the three-winding transformer (TWT). The suggested method also estimates geometrically a complex parameter that is mutual leakage between
