| Abstract: | Multivariate multimodal functions have multiple local extreme points.However,it is easy to fall into a single local extreme point through traditional optimization methods and it’s difficult to meet the global optimization requirements.Genetic algorithm,which has powerful mathematical computing capability,can search the global space to find extreme points and can effectively optimize multivariate multimodal functions.And a wrong conclusion when traditional optimization methods were used in optimization of multivariate multimodal functions can be avoided.Processes and optimization toolbox of genetic algorithm are briefly introduced in this paper.It indicates that the MATLAB-based genetic algorithm is a good global optimization tool by actual programming optimization. |
