Prof. Yuhong Dai Elected as the 2023 Fellow of IFORS

The 23rd International Federation of Operational Research Societies (IFORS) Conference was held on July 10-14, 2023 in Santiago, Chile. The conference announced the new IFORS Fellows with only three recipients selected, including Prof.Yuhong Dai.

 Prof.Yuhong Dai is the Vice President of the Academy of Mathematics and Systems Sciences (AMSS), Chinese Academy of Sciences, President of the Asia-Pacific Federation of Operational Research Societies and the President of the Operations Research of Society of China.

 He has long been engaged in theoretical and applied research on optimization methods, and has made systematic and creative work in nonlinear optimization, integer programming and applied optimization. He developed and improved the theory of nonlinear conjugate gradient methods and proposed the Dai-Yuan method. He developed and improved the theory of gradient methods and proposed the Dai-Fletcher method. He proposed the new direction of least constraint violation optimization and gave the basic theory and algorithms. He solved the open problem on the convergence of the BFGS quasi-Newton method independently and cooperated solved the open problem on the complexity of sequentially lifting cover cut. In 2018, he and his students developed the CMIP, which is the first modern integer programming solver in China. His methods and results have been widely cited by the optimization theory and application communities.

 Prof.Yuhong Dai was invited to give a 45-minute invited talk at the International Congress of Mathematician in 2022, a semi-plenary talk at the 5th International Conference on Continuous Optimization (a flagship conference organized by Mathematical Optimization Society) in 2016, and a plenary talk at the 24th International Symposium on Mathematical Programming (the largest conference of the International Society for Mathematical Optimization) in 2022. He was awarded the Second Prize of National Natural Science of China (completed by Prof. Yaxiang Yuan and Prof. Yuhong Dai), China Youth Science and Technology Award, Shiing-Shen Chern Mathematics Prize, Feng Kang Scientific Computing Prize, the first Xiao Shutie Applied Mathematics Prize, and the Best Paper Prize of the International Congress on Communication.

 The IFORS was founded in 1955, with a long history of more than 60 years, is the only global international organization of operations research. This important world conference is held every three years. IFORS 2023 is to bring together academia, practitioners, and experts in the field of Management Science from more than 60 countries and to contribute to its development through mutual academic and information exchange.

 The IFORS Administrative Committee approved the establishment of the IFORS Fellows Award in 2020. The IFORS Fellows Award serves to recognize a distinguished individual’s contribution to international operational research and its communities. The criteria for selection of the IFORS Fellow include various aspects of research, practice, service, education, and management in operations research. IFORS Fellows are selected annually, and Academician Prof. Yaxiang Yuan and Prof. Xiangsun Zhang from AMSS were elected in 2021.
