Voronoi Tessellation Optimization : A Local/Global Optimization Hybrid for Electromagnetics Design

Abstract

This paper introduces a new hybrid local-global optimizer called the Voronoi Tessellation Optimization (VTO) algorithm which leverages precomputed gradients and a space partitioning technique to improve single objective convergence speed and robustness. VTO has been herein compared with other well-known optimization algorithms used in electromagnetics and optics and has demonstrated commensurate or improved performance on two multimodal test problems.
