Prof. Richard Lorentz (California State University) is
the father of strong computer bots for two rather different games:
Invader for the game of Amazons.
Wanderer for the game of Havannah.
Invader won several medals in the Computer Olympiads for Amazons: Bronze in 2001, 2002, Silver in 2003, 2005, Gold in 2008, 2009, 2010.
Wanderer got the Havannah Silver medal in the Computer Olympiad 2010, and Gold in the inofficial competition of 2009.
Both bots, Invader and Wanderer, contain Monte-Carlo elements. Wanderer is active on littlegolem.net, Invader played a few games on Little Golem, with a 100 % score.
In April 2011, Richard Lorentz (California State University at Northridge) took three weeks of his sabbatical to stay with my group at Jena University. Here are a few pictorial impressions, from his Amazons talk in the seminar.
