Expected improvement ei criterion

http://ash-aldujaili.github.io/blog/2024/02/01/ei/ 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.
