'''LearningLemming''', (Learning Lemming)
a private, experimental and [[Chess Engine Communication Protocol]] compliant chess engine <ref>[http://computer-chess.org/doku.php?id=computer_chess:wiki:lists:private_engine_list Private Engine List] from [[Ron Murawski|Ron Murawski's]] [http://computer-chess.org/doku.php?id=home Computer-Chess Wiki]</ref> by [[Sam Hamilton]] with focus on [[Learning]] techniques, and along with [[Edsel Apostol|Edsel Apostol's]] [[Twisted Logic]], ancestor of [[Hannibal]].

The [[Book Learning|book learning]] feature in LearningLemming is not applied during the game. Instead, parts of the game to learn from are saved to a file, and then a separate learning program does a post-mortem analysis and saves off conclusions for LearningLemming to use in future games. The other type of learning Sam played with in LearningLemming is [[Automated Tuning|parameter tuning]], and a rough form of this is used in the Hannibal development process <ref>[http://www.talkchess.com/forum/viewtopic.php?topic_view=threads&p=411225&t=39469 Re: Hannibal 1.1- Learning Lemming 0.44T - x64] by [[Sam Hamilton]], [[CCC]], June 24, 2011</ref>.
