Zdenek Zdrahal [1]

Zdenek Zdrahal, (Czech: Zdenek Zdráhal)
a Czech British electrical engineer, computer scientist and Senior Research fellow at Knowledge Media Institute [2] , The Open University, Milton Keynes, South East England. His earlier research affiliations include the Czech Technical University in Prague, Czech Republic, until 1992 Czechoslovakia, the University of Edinburgh, Center for Research and Advanced Studies of the National Polytechnic Institute and Ensenada Center for Scientific Research and Higher Education (CICESE) in Mexico [3]. Zdenek Zdrahal research interests include the application of Artificial Intelligence in design, case-based reasoning and knowledge sharing.


In 1979/80 as visiting researcher at the University of Edinburgh, Zdenek Zdrahal worked with Ivan Bratko and Alen Shapiro on Pattern Recognition applied to Chess. In fact they used Bitboards, called cellular 8x8 arrays, to implement their Cellular logic processing emulator for chess (CLESS) [4] . CLESS used three kinds of instructions to recognize simple and more complex chess patterns:

  1. bitwise boolean operations without any interactions between squares
  2. shifts as expand instructions
  3. fill-like propagation instructions, internally using the first two kinds of instructions and conditions in loops
