    Subject to: Martin Grötschel

    Martin Grötschel, born in 1948, studied mathematics at U Bochum (1969-1973), received his PhD in economics (1977) and his habilitation in Operations Research (1981) at U Bonn. He was professor of applied mathematics at U Augsburg 1982-1991, professor of information technology at TU Berlin and vice president/president of the Zuse Institute for Information Technology Berlin (ZIB) 1991-2015. Grötschel was the President of the German Mathematical Society (DMV) 1993-1994, Secretary General of the International Mathematical Union (IMU) 2007-2014, President of the Berlin Brandenburg Academy of Sciences and Humanities (BBAW) 2015-2020 and chaired the DFG Research Center MATHEON “Mathematics for Key Technologies” 2002-2008. He has held numerous further science administration and advisory positions. Grötschel’s main areas of research are discrete mathematics, optimization, and operations research. He has made, e.g., contributions to polyhedral combinatorics and to the development of methods proving the polynomial time solvability of optimization problems. He has also focused on the design of practically efficient algorithms for hard combinatorial optimization problems appearing in practice, such as the travelling salesman, the max-cut, the linear ordering, and various connectivity problems. Cutting plane algorithms for integer programming are among his favorites. The application areas include telecommunications, chip design, energy, production planning and control, logistics, and public transport. He has been an open access and open science activist and is currently involved in fostering digital humanities. Grötschel’s scientific achievements were honored with several distinctions including the Cantor Medal, the Leibniz, the Beckurts, the Dantzig, the Fulkerson, and the John von Neumann Theory Prize. He holds four honorary degrees and is a member of seven scientific academies, including the US National Academy of Engineering.

    Carola Doerr, formerly Winzen, is a CNRS research director in the Computer Science department LIP6 of Sorbonne Université in Paris, France. Carola's main research activities are in the analysis of black-box optimization algorithms, both by mathematical and by empirical means. Specifically, she is very interested in controlling the choice and the configuration of black-box optimization algorithms all along the optimization process -- with and without Machine Learning techniques. She is equally interested in complexity results, running time bounds, good benchmarking practices, empirical evaluations, and practical applications of self-adjusting black-box optimization algorithms. Carola is associate editor of IEEE Transactions on Evolutionary Computation, ACM Transactions on Evolutionary Learning and Optimization (TELO) and Evolutionary Computation. She is/was program chair for the BBSR track at GECCO 2024, the GECH track at GECCO 2023, for PPSN 2020, FOGA 2019 and for the theory tracks of GECCO 2015 and 2017. She has organized Dagstuhl seminars and Lorentz Center workshops. Together with Pascal Kerschke, Carola leads the 'Algorithm selection and configuration' working group of COST action CA22137. Carola's works have received several awards, among them the CNRS bronze medal, the Otto Hahn Medal of the Max Planck Society, best paper awards at GECCO, CEC, and EvoApplications.
