Ingo Althöfer (born 1961) [1] is a German mathematician at the University of Jena, where he holds the chair of operations research. [2]
Althöfer earned his PhD in 1986 at Bielefeld University. His dissertation, Asymptotic Properties of Certain Competition Systems in Artificial Intelligence and Ecology, was supervised by Rudolf Ahlswede. [3]
Contributions
Topics in Althöfer's professional research include the realization of finite metric spaces by shortest path metrics in graphs and their approximation by greedy spanners, [4] algorithmic game theory and combinatorial game theory, [5] and heuristic search algorithms for optimization problems.
Althöfer is also known for his inventions of games and puzzles, including dice game EinStein würfelt nicht!, [6] for his experiments with self-assembly of Lego building blocks by running them through a washing machine, [7] and for his innovations in computer-human chess playing. In the 1990s he tested his "drei hirn" ["3-brains"] system, in which a human decides between the choices of two computer chess players, against strong human players including grandmaster David Bronstein and woman grandmaster Sofia Polgar. [8] In 2004 he and Timo Klaustermeyer introduced freestyle chess, a style of human chess playing allowing arbitrary consultation with computers or other people. [9]
