As previously stated, the acquisition function used to guide the search for the next best points to sample was Expected Improvement (EI). We utilized a batched approach to generate 3 samples at each iteration. By using EI in a batch setting, we aimed to make informed decisions about which points to evaluate next, taking into account both the uncertainty and the potential improvement in the material property. After each round of batch trials were synthesized and characterized, the model was updated with the latest objective values, and a new batch was created.
