Abstract

With the application of global optimization algorithm, the research of parallel optimization algorithm and its realization become very important. In this paper, two kinds of parallel models of parallel integer coded differential evolution strategy, such as master-slave model, coarse-grained model, are proposed and simply evaluated. For engineering problems, the integer coding is efficient, and automatically filters unsteady solutions. They are combined with finite-difference time-domain (FDTD) method to optimize time-domain ultra-wide band (UWB) transverse electromagnetic (TEM) horn antenna. As for the TEM horn antenna to each model, the optimization results are illustrated in order to evaluate them.
