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]
