Both higher-order (pseudo)deterministic and zeroth-order probabilistic optimization methods have been analyzed tested for solving the global problems arising in computational electromagnetics. Previously recommended, but seemingly independent schemes (evolution strategies, simulated annealing, Monte Carlo iteration) unified into a robust general method: evolution strategy (GES). Regularization techniques, stability of solutions, nonlinear phenomena are shown to be topics closely related...
