A PRACTICAL GUIDE TO OPTIMIZATION PROBLEMS WITH DISCRETE OR INTEGER VARIABLES, REVISED AND UPDATED The revised second edition of Integer Programming explains in clear and simple terms how to construct custom-made algorithms or use existing commercial software to obtain optimal or near-optimal solutions for a variety of real-world problems. The second edition also includes information on the remarkable progress in the development of mixed integer programming solvers in the 22 years since the first edition of the book appeared. The updated text includes information on the most recent developments in the field such as the much improved preprocessing/presolving and the many new ideas for primal heuristics included in the solvers. The result has been a speed-up of several orders of magnitude. The other major change reflected in the text is the widespread use of decomposition algorithms, in particular column generation (branch-(cut)-and-price) and Benders’ decomposition. The revised second edition: Contains new developments on column generation Offers a new chapter on Benders’ algorithm Includes expanded information on preprocessing, heuristics, and branch-and-cut Presents several basic and extended formulations, for example for fixed cost network flows Also touches on and briefly introduces topics such as non-bipartite matching, the complexity of extended formulations or a good linear program for the implementation of lift-and-project Written for students of integer/mathematical programming in operations research, mathematics, engineering, or computer science, Integer Programming offers an updated edition of the basic text that reflects the most recent developments in the field.
Founded in the grounds of Magdalen College 500 years ago, Magdalen College School has been educating centuries of students. Originally intended to offer free tuition in grammar, it has attracted students from all walks of life and from all around the UK during its history. From a period of initial success, the fortunes of the school have waxed and waned over the centuries until modern times, where it has become one of the premier independent schools in the country. With former pupils including lord chancellors, film directors, Nobel Prize-winning scientists and noted composers, Magdalen College School has a rich and engaging history, which this book brings to life with colour illustrations and photographs.
Rave reviews for INTEGER AND COMBINATORIAL OPTIMIZATION "This book provides an excellent introduction and survey of traditional fields of combinatorial optimization . . . It is indeed one of the best and most complete texts on combinatorial optimization . . . available. [And] with more than 700 entries, [it] has quite an exhaustive reference list."-Optima "A unifying approach to optimization problems is to formulate them like linear programming problems, while restricting some or all of the variables to the integers. This book is an encyclopedic resource for such formulations, as well as for understanding the structure of and solving the resulting integer programming problems."-Computing Reviews "[This book] can serve as a basis for various graduate courses on discrete optimization as well as a reference book for researchers and practitioners."-Mathematical Reviews "This comprehensive and wide-ranging book will undoubtedly become a standard reference book for all those in the field of combinatorial optimization."-Bulletin of the London Mathematical Society "This text should be required reading for anybody who intends to do research in this area or even just to keep abreast of developments."-Times Higher Education Supplement, London Also of interest . . . INTEGER PROGRAMMING Laurence A. Wolsey Comprehensive and self-contained, this intermediate-level guide to integer programming provides readers with clear, up-to-date explanations on why some problems are difficult to solve, how techniques can be reformulated to give better results, and how mixed integer programming systems can be used more effectively. 1998 (0-471-28366-5) 260 pp.
Male Professionals in Nineteenth-Century Britain is the first statistically-based social, cultural and familial history of a fast-growing and socially prominent section of the Victorian propertied classes. It is built around a representative cohort of 750 men who were recorded in the 1851 census as practising a profession in eight British provincial towns with distinctive economic and social profiles: Brighton, Bristol, Dundee, Greenock, Leeds, Merthyr Tydfil, Winchester, and the twin county town of Northumberland, Alnwick/Morpeth. The book provides a collective account of the cohort's lives and the lives of their families across four generations, starting with their parents and ending with their grandchildren. It touches on the history of 16,000 individuals. The book aims to throw light on the extent to which nineteenth-century professionals had a distinctive socio-cultural profile, as sociologists and some historians have claimed, or were largely indistinguishable from other members of propertied society, as most historians today assume without further investigation. In exploring this question, particular attention is paid to the cohort families' wealth, household size, education, occupational history, geographical mobility, and broader involvement in society measured by their members' choice of marriage partner, their kinship and friendship circles, their political allegiance and their leisure activities. The book demonstrates that male professionals in the Victorian era were far from being a homogenous group, but were divided in many ways. The most important was wealth which played a key role in the social and occupational fortunes of their descendants. These divisions largely explain why some professionals and some individual professions were much more likely to display endogenous characteristics than others. The book also demonstrates that even the most successful professional families got poorer over time, and reveals how easily in the age of industrialisation branches of families and sometimes complete families could drop out of the elite.
Style" is considered one of the greatest guides to writing well. Legendary among writers and critics, but lost for almost 40 years, "Style" is now back in a beautiful new edition, and remains as entertaining and informative as ever.
