'''Ingo Althöfer''',<br/>
a German mathematician, computer scientist, game researcher, game inventor, and full professor at ''Faculy for Mathematics and Computer Science'' <ref>[http://www.minet.uni-jena.de/ Fakultaet fuer Mathematik und Informatik]</ref>, [https://en.wikipedia.org/wiki/University_of_Jena Friedrich Schiller University of Jena] <ref>[http://www.minet.uni-jena.de/www/fakultaet/iam/l_althoefere.html Prof. Dr. Ingo Althöfer - Chair Operations Research]</ref>.
Ingo Althöfer's professional as well as private research interests cover a broad range of AI-issues, [[Search|search]] algorithms, [[Evaluation|evaluation]], creating and inventing new, interesting games such as [[EinStein würfelt nicht!]] <ref>[http://www.3-hirn-verlag.de/MasterGame/regel.html EinStein würfelt nicht] von Ingo Althöfer, Copyright 2004</ref> <ref>[https://www.stmintz.com/ccc/index.php?id=415289 A challenge] to [[Theo van der Storm]]! by Ingo Althöfer, [[CCC]], March 04, 2005</ref> , and triple-brain (3-Hirn) (two- or k-best mode, where an arbiter instance choses from the best moves provided by one or more chess-programs) <ref>[http://www.althofer.de/k-best-visualisations.html K-Best Visualisations]</ref> <ref>[http://groups.google.com/group/rec.games.chess.computer/browse_frm/thread/576a8db8f3b6bef1 A diary on 3-Hirn chess] by [[Ingo Althöfer]], [[Computer Chess Forums|rgcc]], December 27, 1996</ref>. 3-Hirn has become a "brand name" for books, games and software, distributed by Ingo's small publishing company [http://www.3-hirn-verlag.de/ 3-Hirn-Verlag].
