Godfried Theodore Toussaint

It is with great sadness that we share the news that Godfried Theodore Toussaint passed away while sharing his work at the International Cartographic Conference 2019 in Tokyo. He attended ICC2019 to present his work on “The Levenshtein distance as a measure of mirror symmetry and homogeneity for binary digital patterns” in a special session titled “Design & Computation in Geovisualization” convened by the Commission on Visual Analytics.

Godfried Theodore Patrick Toussaint (1944–2019) was a Canadian Computer Scientist, a Professor of Computer Science, and the Head of the Computer Science Program at New York University Abu Dhabi (NYUAD) in Abu Dhabi, United Arab Emirates. He was considered to be the father of computational geometry in Canada. He did research on various aspects of computational geometry, discrete geometry, and their applications: pattern recognition (k-nearest neighbor algorithm, cluster analysis), motion planning, visualization (computer graphics), knot theory (stuck unknot problem), linkage (mechanical) reconfiguration, the art gallery problem, polygon triangulation, the largest empty circle problem, unimodality (unimodal function), and others. Other interests include meander (art), compass and straightedge constructions, instance-based learning, music information retrieval, and computational music theory.
