| Abstract: | A new hybrid genetic algorithm which combines the good property of the global search of genetic algorithm and regional search of conjugate gradient approach was proposed.In order to ensure the diversity of population and improve the velocity of convergence and efficiency,the niche skill was brought out,by which the best operator was better shared and the function was strengthened.Numerical experiment showed that the new method was feasible and efficient. |
| Keywords: | conjugate gradient algorithm(CGA) genetic algorithm(GA) niche technology multimodal function |
