Mark Winands

Mark Henricus Maria Winands,
a Dutch computer scientist, games researcher and associate professor at Maastricht University. Along with I-Chen Wu and Tristan Cazenave, Mark is Editor-in-Chief of the ICGA Journal, and an associate editor of IEEE Transactions on Computational Intelligence and AI in Games . He is author of various game playing programs, most notably his Lines of Action program MIA , successfully competing at ICGA tournaments . Mark researched on Proof-Number Search, and introduced Enhanced Forward Pruning , which applies Forward Pruning Techniques, like Null Move Pruning and Multi-Cut, not only at expected Cut-Nodes, but also at expected All-Nodes with slight modifications on a Principal Variation Search framework, and the Relative History Heuristic in 2004 at the Computers and Games 2004 Conference in Ramat-Gan, an improvement of Schaeffer's History Heuristic considering Dap Hartmann's Butterfly Heuristic.

Mark's Programs

• Lines of Action program MIA , three times winner of the Computer Olympiad
• Clobber program Mila
• Draughts program Rocky
• Surakarta program SIA, gold medal winner from the Amsterdam 2007 Computer Olympiad
