Previously, when
minibatch=True, Optuna only tracked trial results from minibatch evaluations, which limited the Bayesian optimizer's ability to incorporate insights from larger, full evaluations.This update addresses the issue by registering each full evaluation as an independent trial in Optuna. By doing so, the optimizer can now leverage these additional data points to refine its search strategy and improve overall optimization performance.
