Many real-world optimization problems involve noisy objective evaluations and probabilistic constraints, particularly in the form of joint chance constraints, which are computationally expensive to evaluate. In this work, we propose CR-EA-C, a confidence-driven evolutionary algorithm for solving noisy black-box optimiz...

A surrogate-assisted multi-objective optimization approach that leverages symbolic regression (SR) to construct interpretable analytical approximations of expensive black-box functions and uses iterative construction of surrogates and Tchebycheff scalarization along a set of parallel reference vectors to search for wel...

This work proposes to reduce this expense by predicting the lower level Pareto set for a candidate upper level solution directly, in lieu of performing optimization from scratch, which is competitive across a range of problems, including both deceptive and non-deceptive problems.
