optuna.integration.botorch.qehvi_candidates_func(train_x: torch.Tensor, train_obj: torch.Tensor, train_con: Optional[torch.Tensor], bounds: torch.Tensor) → torch.Tensor

Quasi MC-based batch Expected Hypervolume Improvement (qEHVI).

The default value of candidates_func in BoTorchSampler with multi-objective optimization when the number of objectives is three or less.
