return _get_pareto_front_trials(self)
Return trials located at the Pareto front in the study.

        A trial is located at the Pareto front if there are no trials that dominate the trial.
        It's called that a trial ``t0`` dominates another trial ``t1`` if
        ``all(v0 <= v1) for v0, v1 in zip(t0.values, t1.values)`` and
        ``any(v0 < v1) for v0, v1 in zip(t0.values, t1.values)`` are held.

        Returns:
            A list of :class:`~optuna.trial.FrozenTrial` objects.
