Researchers have developed a new cost-aware stopping criterion for Bayesian optimization, termed "EI stopping." This method aims to maximize utility by balancing the best observed score against the cost of each evaluation step. The EI stopping rule advances candidates based on expected improvement, stopping when no further improvement is expected to outweigh the cost. While generally effective, the researchers also devised a correction method to identify when EI stopping might terminate prematurely, particularly at lower costs. AI
