optuna_integration.botorch.qkg_candidates_func

optuna_integration.botorch.qkg_candidates_func(train_x, train_obj, train_con, bounds, pending_x)

Quasi MC-based batch Knowledge Gradient (qKG).

According to Botorch/Ax documentation, this function may perform better than qEI (qei_candidates_func). (cf. https://botorch.org/tutorials/one_shot_kg )
