    acquisition_fucntion_values = mean + acquisition_function_kappa * std

    if study_goal == "MAXIMIZE":
      x_max = x_tries[acquisition_fucntion_values.argmax()]
    elif study_goal == "MINIMIZE":
      x_max = x_tries[acquisition_fucntion_values.argmin()]

When the goal is MINIMIZE, should the acquisition_fucntion_values be mean - acquisition_function_kappa * std ?
