Richard+J.+Lorentz

an American computer scientist and professor of Computer Science at [|California State University, Northridge]. His major research activity involves the study of game playing programming. He is co-author and supervisor of the successful Amazons program [|Invader], co-author of the Havannah program [|Wanderer], and the Dots and Boxes program [|Matadots]. His main interests is to expand Monte-Carlo tree search algorithms that exist in Invader and Wanderer. || toc =Photos= =See also=
