Evolutionary Search with Multiple Utopian Reference Points in Decomposition‐Based Multiobjective Optimization

Abstract: Decomposition-based multiobjective evolutionary algorithms (MOEA/Ds) have become increasingly popular in recent years. In these MOEA/Ds, evolutionary search is guided by the used weight vectors in decomposition function to approximate the Pareto front (PF). Generally, the decomposition function will be constructed by the weight vectors and the reference point, which play an important role to balance convergence and diversity during the evolutionary search. However, in most existing MOEA/Ds, only one ideal poin… Show more

“…Note that most of these algorithms adopt additional reference information (reference vectors, reference points, or weight vectors) during the environmental selection, which helps to maintain the diversity of the population. Due to the advantage with a better mathematical explanation, decomposition-based MOEAs have become very popular in recent years [21][22][23][24].…”

“…Wang et al [23] presented the Pareto adaptive scalarising method (MOEA/D-PaS) which is based on the selection of appropriate norm spaces in order to increase the searching ability. Lin et al [24] improved the effectiveness of the Pareto solution search by using multiple utopian reference points instead of one.…”

“…Pareto optimal solutions (PS) are a set of nondominated solutions for an MOP, and Pareto optimal front (PF) represents their objective values [4][5][6]. To get the optimal solutions of an MOP, many multiobjective evolutionary optimization algorithms (MOEAs) are proposed to evolve a population with multiple solutions, aiming to approximate the true PF [7][8][9]. Due to the advantage of being able to optimize multiple solutions simultaneously, MOEAs have been a widely used approach to solve various kinds of optimization problems, that is, MOEAs based on Pareto dominance relation [10][11][12][13], MOEAs based on performance indicator [14][15][16], and MOEAs based on decomposition [17][18][19][20][21][22][23][24][25].…”
