Sommario/riassunto

With the advent of approximation algorithms for NP-hard combinatorial optimization problems, several techniques from exact optimization such as the primal-dual method have proven their staying power and versatility. This book describes a simple and powerful method that is iterative in essence and similarly useful in a variety of settings for exact and approximate optimization. The authors highlight the commonality and uses of this method to prove a variety of classical polyhedral



results on matchings, trees, matroids and flows. The presentation style is elementary enough to be accessible to anyone with exposure to basic linear algebra and graph theory, making the book suitable for introductory courses in combinatorial optimization at the upper undergraduate and beginning graduate levels. Discussions of advanced applications illustrate their potential for future application in research in approximation algorithms.

Sommario/riassunto

Objects have many stories to tell. The stories of their makers and their uses. Stories of exchange, acquisition, display and interpretation. This book is a collection of essays highlighting some of the collections, and their object biographies, that were displayed in the Uncovering Pacific Pasts (UPP) exhibition.
