Automated Learning of Algebraic Models for Optimization

A software suite developed to generate algebraic models of black-box systems (simulations, experiments, etc.). These surrogate models are developed with the following goals:
  • Accurately represented the black-box output variables over the full design space of input variables
  • To identify a simple, low-complexity surrogates of a system with a, previously, unknown functional form
  • Accomplish the above goals using a minimal data set of, potentially, costly black-box function evaluations
