| 摘 要： | 早熟收敛问题是遗传算法中影响寻优效果的重要因素。分析了变异策略中由经验参考值确定的变异概率对样本多样性的影响，提出了采用自适应变异控制变异算子的方法，阐述了根据进化过程选择变异时机和变异概率的思路。通过实例计算结果的比较，证明了改进自适应变异算法可以有效地解决早熟收敛问题。

| Abstract: | Premature convergence is an important factor affecting optimization results in genetic algorithms(GA) . Effect on sample variety of mutation probability delivered by experience value in mutation method is analyzed, and self adaptation mutation method controlling mutation operator is advanced and how to select mutation time and mutation probability based on evolution process is dealt with. The comparison of the results from actual example calculations has proved that the improved self adaptation mutation algorithms can solve the problem of premature convergence effectively. |
