	The Thesis

About me
• I'm a Senior Research Scientist at GN ReSound Algorithm Research. GN is an international market leader in digital hearing instruments, headsets, and audiological diagnostics equipment.
  I have a Ph.D. degree in Artificial Intelligence from Maastricht University , and a M.Sc. degree in Applied Physics from the Delft University of Technology. For my M.Sc. research I worked in the Pattern Recognition Group on non-linear feature extraction. For my Ph.D. research I worked on computer Go. The research resulted in the thesis 'AI techniques for the game of Go', several publications, and the two Go programs Magog and Migos". The 9x9 Go program Magog participated in several international events, and has won the bronze medal in the 9^th Computer Olympiad. The program Migos was the first program in the world to solve 5x5 Go. In 2008 Migos also found the world's first solutions for 3x7, 4x6, 4x7 and 5x6 (all published human solutions for these boards were wrong). Migos still holds the record for the largest Go boards solved by computer.
  In 2007 I wrote a new Go program called Steenvreter which won the 12^th Computer Olympiad and still performs well in more recent events.
  
  My main interests and expertise are in artificial intelligence, pattern recognition, machine learning, digital signal processing, neural networks, search techniques, games, data mining, perception, and of course computer Go.
