Abstract: In order to solve the problems of poor performance and low universality in solving MOPs with unconventional PF based on decomposed multi-objective evolutionary algorithms,a new Multi-Objective Evolution Algorithm based on Decomposition and Sub-problem Effectiveness Guidance(MOEA/D-SEG) is proposed.The algorithm expands the sub-problem structure and describes the behaviour of weight vectors in the evolutionary process.The weight vector adjustment is realized by fission “efficient” sub-problems,so that the algorithm can better adapt to the multi-objective optimization problems with different characte-ristics,ensure the convergence and diversity of the solution set,and improve the ability of the algorithm to solve various complex multi-objective optimization problems.Through a series of experiments,the effectiveness of the proposed algorithm in different feature testing problems is proved,and the superiority of the proposed algorithm is proved by comparative analysis with other advanced algorithms.The application of the proposed algorithm in steel-making and continuous casting scheduling problem further verifies the feasibility.
