| 摘 要： | 针对遗传规划中群体规模较大。收敛效率较低等特点，提出了对传统遗传规划中初始群体的生成方法的改进．使生成的初始群体具有良好的性能，从而提高遗传规划的收敛效率．通过对两个函数进行符号回归验证，说明此方法是合理可行的．

| Abstract: | This paper presents an improving method for creating initial population in genetic programming so as to decrease the bigger population and accelerate the lower eonvergence rate. The method can enable the initial population to have better efficiency,and it can improve the convergence efficiency of genetic programming. Two examples about symbolic regression given in this paper show that this method is feasible. |

| Keywords: | genetic programming population efficiency |
