Surrogate models expedite the search for promising designs by standing in for expensive design evaluations or #simulations. They provide a global model of some metric of a design—such as weight, aerodynamic drag, or cost—which can then be #optimized efficiently. Written for postgraduate students and engineers our March Book of the Month is a practical guide to using #surrogates in #engineering #design. https://arc.aiaa.org/doi/book/10.2514/4.479557 | AIAA - The American Institute of Aeronautics
