Representative achievements:Following the principle of combining characteristic development, academic research and practical problem solution, the Center has conducted systematic researches on a variety of modern optimization methods and the applications thereof.The team carries out systematic researches in such fields as stability analysis and high-performance algorithm design of multi-stage stochastic optimization and distributionally robust optimization , the results of which have been published in SIAM J. Optim., JOTA, EJOR, JOGO and like journals. This is the only team from China that has been invited for consecutive years to attend the International Conference on Stochastic Programming, and the team leader Professor Chen Zhiping is also the only editorial board member of "OR Spectrum" in Chinese Mainland. The team also consecutively published papers in top international financial journals such as JBF, JEDC, IME and QF. With their outstanding contribution to applying operations research methods to solving complex financial decision-making problems, the team was invited to write a review in the monograph "Optimal Financial Decision Making under Uncertainty" published by Springer. In terms of the research on the graph factor theory, the team simplified the proof of the (g,f)-factor structure theorem of Professor László Lovász, the Wolf Prize winner (the proof is simplified from 24 pages to 5 pages), and Brian Alspach, a globally renowned graph theory expert, called it "good job"; the team’s work on the characterization of graph spectrum was included by Andries E. Brouwer and Willem H. Haemers, two famous algebraic graph theorists, into their monograph "Spectra of Graphs"; the team solved the hypergraph matching conjecture proposed by Professor Vojtěch Rödl, the one-hour speaker of the World Congress of Mathematicians and a member of the American Academy of Science and the Academy of Europe, and solved the well-known Tutte type condition characterization problem, which is evaluated as "I now understand that you are one of the top three researchers in the world of Graph Factors" by Professor Noriaki Kano, an international graph theory expert. And these results were published in SIAM J. Discrete Math. The team has proposed the MOEA/D algorithm, one of the two mainstream algorithms in the field of multi-objective evolutionary algorithms, and the result was published in IEEE Trans. EVC, received the Best Paper Award of the journal in 2010, and has been cited for 4,500 on Google Scholar; and researched multi-objective sparse optimization, adaptive covariance evolution strategy and variable-dimensional optimization problems, the results of which were published in IEEE Trans. NNLS, IEEE Trans. CYB, IEEE Trans. EVC and other journals. The above achievements have been initially applied to complex decision-making problems in the fields such as large enterprise operation management, financial risk management and investment analysis, and optimization of engineering design.
