In this paper, a modified Differential-Evolution approach to solve numerical optimization problems is presented. The aim of the approach is to increase the probability of each parent to generate a better offspring. This is done by introducing time variant scaling factor F, and using a simple but efficient mutation operator which combines information of the both better and worse solution in the population...
The theory design would exceed the practical range in the conventional wideband matching networks design. The improved MEA was adopted to optimize nonuniform broadband impedance transformer in this paper. In the paper the improved self-adaptive similartax strategy was presented at first, which self-adaptive choose the spread range of different subpopulations and control the distance of new individuals...
