Abstract
This thesis considers techniques for parallelizing the discovery of optimal control of microstructures. Microstructure, the arrangement of different phases in a material, governs many of the material's properties. The development of microstructure over time can be modeled by a set of partial differential equations based on the Phase Field model. Due to the high degree of freedom of this model, applying control theory directly is intractable. However, there has been recent research that greatly reduces the complexity of the model while still producing a solution that's close to the the one given by the full-order model. This work seeks to expand on the research to develop an efficient and highly scalable version of the given algorithm.
