Dutch theoretical computer scientist
Paul Michael Béla Vitányi (born 21 July 1944) is a Dutch computer scientist, Professor of Computer Science at the University of Amsterdam and researcher at the Dutch Centrum Wiskunde &amp; Informatica.
Biography.
Vitányi was born in Budapest to a Dutch mother and a Hungarian father. He received his degree of mathematical engineer from Delft University of Technology in 1971 and his Ph.D. from the Free University of Amsterdam in 1978.
Career.
Vitányi was appointed professor of computer science at the University of Amsterdam, and researcher at the National Research Institute for Mathematics and Computer Science in the Netherlands (CWI) where he is currently a CWI Fellow. He was guest professor at the University of Copenhagen in 1978; research associate at the Massachusetts Institute of Technology in 1985/1986; Gaikoku-Jin Kenkyuin (councilor professor) at INCOCSAT at the Tokyo Institute of Technology in 1998; visiting professor at Boston University in 2004, at Monash University in 1996 and at the National ICT of Australia NICTA at University of New South Wales
in 2004/2005; visiting professor at and adjunct professor of computer science at the University of Waterloo from 2005.
Vitányi has served on the editorial boards of "Distributed Computing" (1987–2003), "Information Processing Letters"; the "Theory of Computing Systems"; the "Parallel Processing Letters"; the "International journal of Foundations of Computer Science"; the "Entropy"; the "Information"; the " SN Computer Science"; the "Journal of Computer and Systems Sciences" (guest editor), and elsewhere.
Work.
Vitányi has worked on cellular automata, computational complexity, distributed and parallel computing, machine learning and prediction, physics of computation, Kolmogorov complexity, information theory and quantum computing, publishing over 200 research papers and some books. As of 2020 his work on normalized compression distance was used in 15 US patents and on 
normalized Google distance in 10 US patents.
Together with Ming Li he pioneered theory and applications of Kolmogorov complexity. They co-authored the textbook "An Introduction to Kolmogorov Complexity and Its Applications", parts of which have been translated into Chinese, Russian and Japanese. The textbook 
received the William Holmes McGuffey Longevity Award of the Textbook &amp; Academic Authors Association (TAA) (2020), and the Chinese translation received the National Outstanding Scientific and Technological Book Award of the People's Republic of China (1999).
