摘 要: 在传统遗传算法 (GeneticAlgorithms,GA)基础上引入模拟退火技术 (SimulatedAnnealing,SA) ,提出了遗传模拟退火算法 (GSA) ,并将其应用到水质模型参数估值中。计算结果表明 ,GSA法综合了 2种优化方法各自的优点 ,不但克服了传统GA容易早熟的缺点 ,还加强了算法的收敛速度 ,因而具有良好的优化性能。不同的参数估值方法比较进一步验证了新方法的有效性。 GSA is introduced in this paper based on the combination of genetic algorithms (GA) and simulated annealing algorithms (SA).The paper also applies GSA to estimating parameters for water quality models.Results show that GSA integrates the advantages of two algorithms,which can avoid premature in GA and has better optimizing capability and faster convergence rate.Thus the validity of GAS has been testified using different parameter estimation methods.As one of the modern optimization approaches,GAS would have its extenstive application prospects in the field of in environmental optimization.
