From its modest beginning in March 1970, alternating between Louisiana State University and Florida Atlantic University for two decades, it soon found its longtime home at the FAU campus in Boca Raton, Florida, organized every March by Professor Fred Hoffman. Researchers in the areas covered by the conference gather each year to lecture on their recent results, and to collaborate on future ideas and work on ongoing joint projects. Participants have included researchers from hundreds of colleges and universities, businesses, industry, and government agencies, as well as graduate, undergraduate, and high school students. The conference’s five days are full of academic activity. There are plenary lectures by researchers in the field at various stages of their careers, from rising young stars to distinguished veteran contributors to the disciplines, along with leaders in related fields with exciting results to communicate. Parallel sessions of contributed papers are presented throughout the week, including several special sessions highlighting selected areas of research, or organized according to some other theme. To promote informal joint discussions, the conference organizes evening social events, an optional afternoon excursion, and problem sessions, with the intention to disseminate and stimulate research and foster collaboration. The conference has achieved much success in this regard, planting the seeds of many books, articles, and new ideas. A volume of 21 research surveys by leading experts [1] has been published in celebration of the 50th conference, capturing some of the flavor of the areas that have been presented at the SEICCGTC over its many years. It affords readers an idea of the breadth and depth of what has been presented at the conference and outside it, as well B Martin Charles Golumbic golumbic@gmail.com 1 University of Haifa, Mt.
