基因算法是基于自然选择和自然基因机制的模型参数优化估计的通用数值方法,具有许多优点。它的主要缺点是,模型参数初始变化区间的大小对寻优效果有显著影响.文中改进了基因算法,并对具有寻优特性及其在水文建模中的应用进行了初步研究。
Genetic algorithm is a general numerical method based on the optimization of model parameters of natural selection and natural gene mechanism, which has many advantages. Its main disadvantage is that the size of the initial variation of the model parameters has a significant effect on the optimization effect.In this paper, the genetic algorithm is improved, and the optimization characteristics and its application in hydrological modeling are preliminarily studied.
