The 2020 S. Barry Cooper Prize is awarded to Bruno Courcelle for his
work on the definability of graph properties in Monadic Second Order
Logic, through a sequence of seminal papers and a book (joint with Joost
Engelfriet).  This forms an outstanding example of theory building,
bringing together logic, computability, graph grammars, and various
notions of graph width (tree-width, clique-width and rank-width) and
opening new avenues in our understanding of graph structure theory and
the computability and complexity of graph algorithms.  Besides its
foundational character, the work has had great impact on a number of
areas of computer science, including in parameterized algorithmics,
verification and other areas, and has influenced a generation of
researchers in this field.  It has straddled the divide between the
logical and algorithmic aspects of theoretical computer science.

The award ceremony will take place on July 2nd during the Computability
in Europe 2020 conference.
Registration at the conference
(https://www.acie.eu/cie-conference-series/cie2020) is mandatory to
attend, but it is without fees.
