Abstract
Nowadays, most approaches in the evolutionary multiobjective optimization literature concentrate mainly on adapting an evolutionary algorithm to generate an ap-proximation of the Pareto frontier. However, this does not solve the problem. We present a new idea to incorporate into a MOEA the Decision Maker (DM) preferences, ex-pressed in a set of solutions assigned to ordered catego-ries. We modified the Non-dominated Sorting Genetic Algorithm 2 (NSGA2) to make selective pressure towards non-dominated solutions that belong to the most preferred category. In several instances, on the project portfolio problem, our proposal outperforms the standard NSGA2, achieving non-dominated solutions that best match the DM’s preferences.
