Combinatorics, Graph Theory and Computing

This proceedings volume gathers selected, revised papers presented at the 51st Southeastern International Conference on Combinatorics, Graph Theory and Computing (SEICCGTC 2020), held at Florida Atlantic University in Boca Raton, USA, on March 9-13, 2020. The SEICCGTC is broadly considered to be a trendsetter for other conferences around the world - many of the ideas and themes first discussed at it have subsequently been explored at other conferences and symposia. The conference has been held annually since 1970, in Baton Rouge, Louisiana and Boca Raton, Florida. Over the years, it has grown to become the major annual conference in its field, and plays a major role in disseminating results and in fostering collaborative work. This volume is intended for the community of pure and applied mathematicians, in academia, industry and government, working in combinatorics and graph theory, as well as related areas of computer science and the interactionsamong these fields.

Auteur

Frederick Hoffman is Professor of mathematical sciences at Florida Atlantic University, Boca Raton, USA. He obtained his PhD in Mathematics (1964) from the University of Virginia, USA. Dr. Hoffman directed thirty-five of the Southeastern International Conferences on Combinatorics, Graph Theory and Computing. He was one of the founding faculty of the FAU Computer Science Department, and a founding fellow of The Institute of Combinatorics and its Applications. His research interests focus on finite groups, combinatorics and applications, and artificial intelligence.
