Abstract
Maintaining the benefits of derivative-free optimization in higher-dimensional decision spaces presents challenges for existing optimization methods. We introduce CUATRO_PLS - an extension of the CUATRO quadratic trust region optimizer that leverages intrinsic structures across high-dimensional black-box variables. CUATRO_PLS shows competitive convergence with leading derivative-free optimization algorithms in three high-dimensional chemical engineering case studies even in the absence or underestimation of known intrinsic dimensionality and is significantly faster than other model-based derivative-free optimization algorithms.
