Abstract

Results are presented that establish clearly the nature of the multiple optima problem for the research conceptual rainfall-runoff (CRR) model SIXPAR. These results suggest that the CRR model optimization problem is more difficult than had been previously thought and that currently used local search procedures have a very low probability of successfully finding the optimal parameter sets. The performance of three existing global search procedures are evaluated on the model SIXPAR. A powerful new global optimization procedure is presented, entitled the shuffled complex evolution (SCE-UA) method, which was able to consistently locate the global optimum of the SIXPAR model, and appears to be capable of efficiently and effectively solving the CRR model optimization problem. -from Authors
