AN EFFICIENT HYBRID SWARM INTELLIGENCE-GRADIENT OPTIMIZATION METHOD FOR COMPLEX TIME GREEN'S FUNCTIONS OF MULTILAYER MEDIA

Abstract

A new hybrid technique for optimization of a multivariable function is proposed. This method is applied to the problem of complex time Green's function of multilayer media. This technique combines Particle Swarm search algorithm with the gradient based quasi-Newton method. Superiority of the method is demonstrated by comparing its results with other optimization techniques.
