Discussion of 'Applying Particle Swarm Optimization to Parameter Estimation of the Nonlinear Muskingum Model' by H.-J. Chu and L.-C. Chang

摘要

Using an accurate and standard solution method is essential to the parameter estimation by various optimization techniques. The numerical results presented herein show that Euler's method is not accurate enough to solve the nonlinear Muskingum model. Hence two methods are proposed to solve the model. Since the fourth-order Runge-Kutta method is an explicit method it is preferable to use for simulation or parameter estimation.
