“…As uniformity increases, potentially, the opposite effect on cardinality may emerge. Furthermore, Kidd et al (2020) proved that, when comparing two representation, R (N ) and R (Z), with the same cardinality, where…”

“…Hence, apart from usually small and linear problems, the full non-dominated set is not practical to compute in a reasonable amount of time. As a result, there are two classes of generation methods, one that aims to determine the whole set of nondominated solutions (the so called Pareto front), and the other which focuses on obtaining a set of solutions representative of the non-dominated set without being overwhelming for the DM (Alves and Clímaco, 2007;Kidd, Lusby and Larsen, 2020). To address the latter, the representation problem must be considered, which, in itself is a multi-objective problem with three objective functions: cardinality, the number of solutions presented to the DM; coverage, how well the complete Pareto frontier is being represented by the set of solutions; and uniformity, how well those solutions are spread through the Pareto front space (Sayın, 2000).…”

“…A classification of optimization problems can be performed by considering the nature of elements in set S. More specifically, an optimization problem is characterized as continuous when S contains real values and as discrete when S includes discrete values, such as integers (Baron et al, 2019;Kidd et al, 2020).…”
