The exact nadir objective vector of a multi-objective discrete optimization problem (MODOP) is crucial for decision-making but remains challenging to find. Existing methods for tackling this issue have limitations in theoretical guarantees or high computational costs. This paper applies boundary dec…
The nadir objective vector plays a key role in solving multi-objective optimization problems (MOPs), where it is often used to normalize the objective space and guide the search. The current methods for estimating the nadir objective vector perform effectively only on specific MOPs. This paper revea…
The decomposition-based multi-objective evolutionary algorithm (MOEA/D) transforms a multi-objective optimization problem (MOP) into a set of single-objective subproblems for collaborative optimization. Mismatches between subproblems and solutions can lead to severe performance degradation of MOEA/D…
