【Abstract】 A simulated evolutionary algorithm is introduced for real valued function optimization. Natural evolution is a optimization process based on population. Simulating this process on a computer has led to stochastic optimization techniques. Compared with classical methods,a simulated evolutionary algorithm converges to global optimum,fits for complex practical problems. Bandwidth optimization is for searching agrid a optimum grid point sequence,so as to obtain minimum bandwidth. Classical methods generally converge to local minimum bandwidth,while the simulated evolutionary algorithm can seach the global optimum solution.更多还原
