Ralph Gasser
Ralph Gasser,
a Swiss computer scientist and software engineer at Google [1]. He holds a Ph.D. in 1995 from ETH Zurich under Jürg Nievergelt, where he researched on exhaustive search and retrograde analysis in computer games, that is forward and backward search. In 1993, he solved the game Nine Men’s Morris that way, using retrograde analysis searching from the terminal nodes and alpha-beta from the root [2]. His Nine Men’s Morris program Bushy already won the Gold medal at the 3rd Computer Olympiad, Maastricht 1991.
