Combinatorial Optimization -- Eureka, You Shrink!

During Aussois 2001, Jack con?rmed: Eureka you shrink! is really true, except that instead of Eureka it maybe was some less digni?ed word. Aussois 2001 was the ?fth in an annual series of workshops on combinatorial optimization that are alternately organized by Thomas Liebling, Denis Naddef, andLaurenceWolsey theinitiatorsofthisseries inevenyearsandtheeditors of this book in odd years (except 1997). We decided to dedicate Aussois 2001 to Jack Edmonds in appreciation of his groundbreaking work that laid the foundations of much of what combinatorial optimizers have done in the last 35 years. Luckily, Jack is a regular participant of the Aussois workshops and, as ever, he cares a lot for young combinatorial optimizers who traditionally play a major r ole in the Aussois series. Fig.1. Handout for the Aussois 2001 participants VI Preface Highlights of Aussois 2001 included a special session entitled Eureka you shrink! in honor of Jack and a special lecture by Jack on Submodular Fu- tions, Matroids, and Certain Polyhedra that closed the workshop. In this book, we give an account of the Eureka you shrink! session as well as reprints of three hardly accessible papers that Jack gave as a handout to the Aussois 2001 participants and that were originally published in theProceedings oftheCalgaryInternationalConferenceonCombinatorialStructuresandTheir Applications 1969, Gordon and Breach (1970) newly typeset by the editors and reprinted by permission.
