| Abstract: | The characteristics of GA (Genetic Algorithm) and the method how to realize it are introduced. For the shortcoming of local - convergence in the progress of GA optimization, the measure of reserving the best individual and changing parameters setting is adopted. A example was cited to proved it. Thus, the searching efficiency of GA and the reliability of getting global - convergence are improved remarkably. |
