Within the optimization community, the question of how to generate new optimization problems has been gaining traction in recent years.

A Parallel Technique for Multi-objective Bayesian Global Optimization: Using a Batch Selection of Probability of Improvement

no code implementations7 Aug 2022 Kaifeng Yang, Guozhi Dong, Michael Affenzeller

This paper proposes five alternatives of \emph{Probability of Improvement} (PoI) with multiple points in a batch (q-PoI) for multi-objective Bayesian global optimization (MOBGO), taking the covariance among multiple points into account.
