recommendations! Published in 2024 at "Structural and Multidisciplinary Optimization"

DOI: 10.1007/s00158-024-03745-7

Abstract: In optimizing real-world structures, due to fabrication or budgetary restraints, the design variables may be restricted to a set of standard engineering choices. Such variables, commonly called categorical variables, are discrete and unordered in essence,… read more here.
