none1Device optimization using metaheuristic methods has been successfully applied to
electromagnetic devices since their development in the early 1980s. Some recent examples of
the application of metaheuristics in electromagnetic device design include, among others,
genetic algorithms [Zaoui2007], evolution strategies [Coelho2007], Tabu search
[Cogotti2000], artificial immune systems [Campelo2006], particle swarm optimization (PSO)
[Ciuprina2002].
In this chapter the author summarizes some of his experiences in the use of two stochastic
optimization techniques which are very suitable to typical electromagnetic devices and
systems. First the algorithms are briefly introduced and then their application to typical
challenging problems, including Polymer Exchange Membrane Fuel Cells (PEMFC), high-
field-uniformity solenoids and Superconducting Magnetic Energy Storage (SMES) systems,
is presented.noneP. AlottoAlotto, Piergiorgi
