| 中文摘要: |
| 给出了利用演化计算方法求解河流水质多参数反问题的一种新方法。该方法把参数识别反问题转化为优化问题用演化方法求解。它的特点在于：从多个初始点开始寻优，并借助交叉和变异算子来获得水质参数的全局最优解。数据模拟结果表明，该方法具有很高的精度，收敛速度快，且编程简单，易于计算机实现，值得在实际工作中采用。 |
| 英文摘要: |
| A new approach based on evolutionary algorithm for inverse problem of parameter identification for water quality model is proposed. It transforms the inverse problem of parameter identification into solution of optimization problem using evolutionary algorithm. By using the evolutionary algorithm the method can search the best solution from many initial points and obtains the total optimum solution of water quality model parameter by means of crossover and mutation operator. The results of numerical simulation show that the method has higher accuracy and quicker convergent speed than existing methods and is easy to program and calculate. |
