Melanie Mitchell is a professor of computer science at Portland State University
. She has worked at the Santa Fe Institute
and Los Alamos National Laboratory
. Her major work has been in the areas of analogical reasoning, Complex Systems
, genetic algorithms and cellular automata, and her publications in those fields are frequently cited.
She received her PhD in 1990 from the University of Michigan under Douglas Hofstadter
and John Holland
, for which she developed the Copycat
cognitive architecture. She is the author of "Analogy-Making as Perception", essentially a book about Copycat
. She has also critiqued Stephen Wolfram
