题目:Let Darwin and the Bees Help Improve your Designs: Nature Inspired Optimization Techniques in 
             Antenna Engineering (借助达尔文和蜜蜂来改进设计:天线工程中由自然界启示的优化技术)

 Engineers are constantly challenged with the temptation to search for optimum solution for complex engineering system designs. The ever increasing advances in computational power have fueled this temptation.  The well-known brute force design methodologies are syste-matically being replaced by the state-of-the-art Evolutionary Optimization (EO) techniques. In recent years, EO techniques are finding growing applications to the design of all kind of systems with increasing complexity. Among various EO’s, nature inspired techniques such as Genetic Algorithms (GA) and Particle Swarm Optimization (PSO) have attracted considerable attention.  GA utilizes an optimization methodology which allows a global search of the cost surface via the mechanism of the statistical random processes dictated by the Darwinian evolutionary concept (adaptation, selection, survivability and mutation). PSO is a robust stochastic evolutionary computation technique based on the movement and intelligence of swarms of bees looking for the most fertile feeding location applying their cognitive and social knowledge.  This presentation will focus on: (a) an engineering introduction to GA and PSO by describing in a novel fashion the underlying concepts and recent advances for those who have used these techniques and for those who have not had any experiences in these areas, (b) demonstration of the potential applications of GA’s and PSO’s to a variety of electromagnetic and antenna designs and (c) assessment of the advantages and the limitations of these techniques.
