On the Computational Complexity of Multi-Objective Ordinal Unconstrained Combinatorial Optimization Open
Multi-objective unconstrained combinatorial optimization problems (MUCO) are in general hard to solve, i.e., the corresponding decision problem is NP-hard and the outcome set is intractable. In this paper we explore special cases of MUCO p…
