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]
Topics in Althöfer's professional research include the realization of finite metric spacesbyshortest 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-assemblyofLego 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]
He has also self-published other books through his personal publishing company, 3-Hirn Verlag, and is one of the editors of the multi-volume book series Rudolf Ahlswede’s Lectures on Information Theory.
