Application of Discrete Fourier Series for Surrogate Modeling

Eldin Wee Chuan Lim
Abstract—A new methodology for deriving surrogate models for solving black-box optimization problems has been developed in this study. A discrete Fourier series was derived from the conventional Fourier series formulation and principles associated with the discrete Fourier transform, and used for the reformulation of black-box objective functions as continuous functions. A stochastic global optimization technique known as Particle Swarm Optimization (PSO) was then applied to locate the global optimal solutions of the continuous functions derived. The methodology was applied to the solution of a black-box optimization problem that was simulated on the basis of the Himmelblau function.
