把最速下降法与遗传算法相结合 ,提出了一种混合算法 ,该算法能使遗传算法离开“早熟收敛”状态 ,最终获得全局最优 .对算法的收敛性进行了证明 ,数值仿真表明算法是有效的 Combining the steepest descent method and the genetic algorithm, a hybrid algorithm is proposed, in which the genetic algorithm can leave the state of “premature convergence” and eventually obtain the global optimum. The convergence of the algorithm is proved, and the numerical simulation shows that the algorithm is Effective
