BEAUSOLEIL, Ricardo P.. Interactive multiobjective tabu: scatter Search based on reference point. Rev. Mat [online]. 2014, vol.21, n.2, pp.261-282. ISSN 1409-2433.

This paper presentsmultiobjective tabu/scatter search architecture with preference information based on reference points for problems of continuous nature. Features of this new version are: its interactive behavior, its deterministic approximation to Pareto-optimality solutions near the reference point, and the possibility to change progressively the reference point to explore different preference regions. The approach does not impose any restrictionswith respect to the location of the reference points in the objective space. On 2-objective to 10-objective optimization test problems the modified approach shows its efficacy and efficiency to find an adequate non-dominated set of solutions in the preferred region.

Keywords : multiple objectives; metaheuristics; reference point; continuous optimization.
