摘要
针对传统推求暴雨强度计算模型的参数的方法,不仅计算复杂、通用性差且常得不到全局最优解等问题,提出利用基因表达式编程对单一重现期暴雨强度计算模型参数的拟合优化的GEP_FPO算法,讨论了该算法的最优化特性和实施过程,并进行了实例计算评估分析,验证了基因表达式编程在单一重现期暴雨强度计算模型参数的拟合优化问题中是可行的,且效果较好。
Based on Gene Expression Programming, an algorithm (GEP_FPO) is proposed for the parametric optimization of the storm intensity model with single return period to overcome the shorta- ges of complex, non-universal and not so accurate of the traditional method. The optimization char- acteristic and implementation process of the presented algorithm were presented. Fit analysis demon- strated that the method is good for practical engineering applications and superior to the traditional methods.
