We study the refractive index sensitive transmission of a 3D
plasmonic crystal, which can exhibit strong optical responses near certain wavelengths and are used in chemical sensing applications. Our goal is to design a a square array of subwavelength cylindrical nanowells in a polymer conformally coated with a gold film that maximizes the optical response.

Every choice of design parameters requires the solution of a 3D finite-difference time-domain simulations that runs for 12 hours of wall-clock time on a 125-nopde linux cluster. We reveal "How the Optimization Was Won" using low-tech tools such as email, matlab, and AMPL.
