Abstract
A method and system for optimizing structural parameters of a physical device is described. The method includes receiving an initial description of the physical device that describes structural parameters of the physical device within a simulated environment. The method further includes performing an operational simulation of the physical device in response to an excitation source, performing an adjoint simulation by backpropagating a placeholder metric through a simulated environment to determine a loss gradient, updating the loss gradient based, at least in part, on a loss metric determined from the operational simulation. Additionally, the method further comprises computing a structural gradient corresponding to an influence of changes in the structural parameters on the loss metric and generating a revised description of the physical device by updating the structural parameters based on the structural gradient to reduce the loss metric.
