MOEA/HD: A Multiobjective Evolutionary Algorithm Based on Hierarchical Decomposition

Abstract: Recently, numerous multiobjective evolutionary algorithms (MOEAs) have been proposed to solve the multiobjective optimization problems (MOPs). One of the most widely studied MOEAs is that based on decomposition (MOEA/D), which decomposes an MOP into a series of scalar optimization subproblems, via a set of uniformly distributed weight vectors. MOEA/D shows excellent performance on most mild MOPs, but may face difficulties on ill MOPs, with complex Pareto fronts, which are pointed, long tailed, disconnected, or… Show more

“…To further confirm the value of our approach, we also used the mean percentile ranking (MPR), an evaluation index based on recall, to evaluate the performance of the algorithm. This evaluation index has been applied in recommendation algorithm and analyses of the performance for predicting drug-targets (Hu et al, 2008;Johnson, 2014;Li et al, 2015;Ding et al, 2017;Hao et al, 2019;Liu et al, 2019b;Liu et al, 2019c; and disease biomarkers (Chen et al, 2016;Zeng et al, 2016;Hong et al, 2019;Xu et al, 2019). For each disease, the genes were ranked in descending order according to the calculated gene-disease predictive value.…”

“…Note that is set to be a very small number, say 10 −6 , in case = 0. Actually, in most existing MOEA/Ds [19][20][21][22][23][24][25], the ideal reference point is usually used as the initial point of all weight vectors, which is estimated by using the best value of each objective found so far during evolution. Note that all the solutions should be dominated by the ideal reference point in the objective space.…”

“…In IMOEA/DU [22], a crossover operator based on uniform design and selection strategy based on decomposition are used to help MOEAs to improve the search efficiency. Recently, in MOEA/HD [23], subproblems are layered into different hierarchies, aiming to better balance convergence and diversity during evolution. In MOEA/D-CPDE [24], the best individual in each generation will be regarded as a seed, which will evolve two individuals by cloud generator.…”

“…The second idea for solving LMOPs is problem transformation, which aims to convert the original LMOP into a small-scale problem, so that it can be handled by general optimizers. Different from traditional decomposition based MOEAs (e.g., those based on hierarchical decomposition [9] or Minkowski distance [10]) using a set of weights to transfer multi-objective optimization into single-objective optimization, WOF [11] uses a set 0000-0000/00$00.00 c ⃝ 0000 IEEE of weights to alter the decision variables, where each weight is related to multiple decision variables and the number of weights is much smaller than the number of decision variables. As a result, a small-scale problem can be established by considering the weights as variables to be optimized.…”
