加速基因方法在最大流量频率曲线参数估计中的应用

Application of Accelerative Genetic Algorithm in Estimating Parametersof Annual Maximum Flow Frequency Curve

基因方法是基于自然选择和自然基因机制的并行随机自适应工程模型参数全局优化估计的通用数值方法。它不限制模型结构、优化准则、被估参数的数目、约束条件等，已开始广泛用于各种工程模型的优化设计之中。文中对它的原理、步骤、特点进行初步探讨，并针对基因方法的弱点，作者提出予以改进的加速基因方法。

Genetic Algorithm is a random multipoint optimal method for estimating parameters of engineering models. Its characteristics are studied and its improved method is made. It is used to estimate the parameters of annual maximum flow frequency curve very well. It may be applied in different engineering models.
