Abstract: Different optimization algorithms are applied to determine the best configuration of a shielding device for eddy currents. The algorithms include seven stochastic binary optimizers, which are based on the concept of genetic algorithms and evolutionary strategies, as well as one quasi-deterministic optimizer based on an algorithm inspired by hill-climbing strategies. The comparison of results obtained from each algorithm shows a very high probability of finding global optima when a special quasi-deterministic algorithm is applied.
