In multiobjective optimization, what does a Pareto optimal solution refer to? A solution that achieves the maximum value of all objectives simultaneously. A solution that is dominated by other solutions in all objectives. A solution that achieves the minimum value of at least one objective. A solution that cannot be improved in any objective without worsening another.
