| Abstract: | With an aim at the problem of the stage-discharge relation curve fitting,this paper suggests the least squares chaos algorithm(LSCA) suitable for curve fitting based on the combination of the least squares(LS) with chaos algorithm(CA),and also the comparison is made of the fitting results by the least squares algorithm and genetic algorithm.The results indicate that the least squares chaos algorithm is characterized by simplicity,quickness and practicality,which is an excellent and global optimization method and also adapts to parameter rating of non-linear relationship. |
| Keywords: | least squares chaos algorithm stage-discharge relation curve fitting |
