The video distinguishes them by their attainability and position relative to the Pareto front. Unattainable solutions are points in the objective-value plane that cannot be achieved by any feasible decision, lying beyond the attainable frontier.

Conditions: The plot is in objective-value coordinates.; The example concerns attainable solutions of a multi-objective problem.; Both objectives are being minimized in the example.
