Summary

• What is new: Use of Multilevel Monte Carlo (MLMC) to enhance multi-step look-ahead Bayesian optimization (BO) efficiency.
• Why this is important: Nested operations in multi-step look-ahead BO methods decrease the efficiency of naive Monte Carlo due to complexity rate degradation.
• What the research proposes: Applying MLMC to achieve canonical Monte Carlo convergence rates independently of dimension and without smoothness assumptions.
• Results: Numerical verifications show MLMC’s benefits for BO across various benchmark examples.
