Martin Grötschel (born September 10, 1948 in Schwelm ) is a German mathematician . From 1991 to 2012 he was Vice President and from 2012 to 2015 President of the Konrad Zuse Center for Information Technology (ZIB). He has been President of the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW) since October 1, 2015 .
Grötschel studied mathematics and economics at the Ruhr University in Bochum from 1969 to 1973 . In 1977 he received his doctorate from the University of Bonn with a dissertation on optimization in economics; In 1981 he completed his habilitation in Bonn with a thesis in the field of Operations Research . A year later he accepted a chair for applied mathematics at the University of Augsburg . From 1991 until his retirement at the end of September 2015, he held the chair for information technology at the TU Berlin. Martin Grötschel was a member of the board of the German Mathematicians Association from 1989 to 1996 and its chairman from 1993 to 1994. From 1999 to 2014 he was a member of the Executive Committee of the International Mathematicians Union (IMU) and from 2007 to 2014 (as the first German) IMU General Secretary. He has been a member of the board of the Einstein Foundation Berlin since 2011 and chaired the board from 2011–2015. He was a co-founder and longstanding spokesman for the DFG Research Center Matheon (since 2014 only Matheon).
Martin Grötschel has been married to his wife Iris Grötschel since 1976 and has three daughters.
Martin Grötschel is considered to be one of the most prominent international representatives of combinatorial optimization .
In mathematical terms, Martin Grötschel mainly worked on problems in graph theory , linear and mixed-integer optimization and operations research . Already in his doctoral thesis, Grötschel was able to achieve significant progress in the development of solution methods for the traveling salesman problem , in particular he contributed a lot to the understanding of cutting plane methods . His joint publications with L. Lovász and A. Schrijver on the ellipsoid method and its application in combinatorial and convex optimization have received worldwide attention. In the last few years, Martin Grötschel has dealt with "classic" mathematical problems, especially with questions of mathematical modeling and the solution of real problems in business and industry. The questions he deals with include the optimization of production processes, optimization problems in local public transport and logistics, the control of CNC machines and robots, the reduction of energy consumption, the optimization of telecommunications networks and frequency planning in mobile communications.
Since the early 1990s, Grötschel has dealt intensively with issues of electronic information and communication, library systems, open access and open science and has been involved in many national and international committees on this topic.
honors and awards
In the course of his research career, Martin Grötschel has received numerous awards for his contributions to mathematical optimization, including the Fulkerson Prize in 1982, the George B. Dantzig Prize in 1991 and the Gottfried Wilhelm Leibniz Prize of the German Research Foundation 1995. In 2004 Grötschel received the EURO Gold Medal from the Association of European Operational Research Societies. In 2006 he received the "Alwin Walther Medal" from the TU Darmstadt and the " John von Neumann Theory Prize " from the Institute for Operations Research and Management Science. In 2006 he was awarded an honorary doctorate from the University of Karlsruhe , in 2007 from the Vietnamese Academy of Sciences and Technology, in 2008 from the Otto von Guericke University Magdeburg and in 2011 from the University of Augsburg . In 1998 he became an honorary member of the DMV. He has been a Distinguished Affiliated Professor at the Technical University of Munich since 2011 .
He has been a full member of the Berlin-Brandenburg Academy of Sciences since 1995 , Foreign Member of the National Academy of Engineering (NAE), USA since 1999 , member of the German Academy of Engineering Sciences (acatech) since 2003, member of the National Academy of Sciences Leopoldina since 2005 , since 2015 Foreign Member of the Chinese Academy of Sciences , since 2016 Fellow of The World Academy of Sciences (TWAS) for the advancement of science in the developing world and since 2017 member of the Academy of Europe Academia Europaea .
In 2008 Grötschel received the Berlin Science Award and the Golden Badge of Honor from the Technical University of Berlin . In 2014, Martin Grötschel received the heureka Foundation's Life Time Award for outstanding scientific achievements in the development and implementation of decision-making and optimization methods in the transport sector.
