Webare observed. Expected improvement (EI) [13] is one of the most widely-used Bayesian optimization algorithms. It is a greedy improvement-based heuristic that samples the point offering greatest expected improvement over the current best sampled point. EI is simple and readily implementable, and it offers reasonable performance in practice. WebAbstract: The expected improvement (EI) is a well established criterion in Bayesian global optimization (BGO) and metamodel assisted evolutionary computation, both applied in optimization with costly function evaluations. Recently, it has been adopted in different ways to multiobjective optimization.
