"This volume contains some key essays by French thinker Edgar Morin on the subject of complexity, and specifically on what Morin calls complex thought."--Pub. desc.

“If you liked Chaos, you’ll love Complexity. Waldrop creates the most exciting intellectual adventure story of the year” (The Washington Post). In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell—and what the origin of life some four billion years ago can tell us about the process of technological innovation today. This book is their story—the story of how they have tried to forge what they like to call the science of the twenty-first century. “Lucidly shows physicists, biologists, computer scientists and economists swapping metaphors and reveling in the sense that epochal discoveries are just around the corner . . . [Waldrop] has a special talent for relaying the exhilaration of moments of intellectual insight.” —The New York Times Book Review “Where I enjoyed the book was when it dove into the actual question of complexity, talking about complex systems in economics, biology, genetics, computer modeling, and so on. Snippets of rare beauty here and there almost took your breath away.” —Medium “[Waldrop] provides a good grounding of what may indeed be the first flowering of a new science.” —Publishers Weekly

New and classical results in computational complexity, including interactive proofs, PCP, derandomization, and quantum computation. Ideal for graduate students.

"Put together one of the world's best science writers with one of the universe's most fascinating subjects and you are bound to produce a wonderful book. . . . The subject of complexity is vital and controversial. This book is important and beautifully done."—Stephen Jay Gould "[Complexity] is that curious mix of complication and organization that we find throughout the natural and human worlds: the workings of a cell, the structure of the brain, the behavior of the stock market, the shifts of political power. . . . It is time science . . . thinks about meaning as well as counting information. . . . This is the core of the complexity manifesto. Read it, think about it . . . but don't ignore it."—Ian Stewart, Nature This second edition has been brought up to date with an essay entitled "On the Edge in the Business World" and an interview with John Holland, author of Emergence: From Chaos to Order.

Briefly, we review the basic elements of computability theory and prob ability theory that are required. Finally, in order to place the subject in the appropriate historical and conceptual context we trace the main roots of Kolmogorov complexity. This way the stage is set for Chapters 2 and 3, where we introduce the notion of optimal effective descriptions of objects. The length of such a description (or the number of bits of information in it) is its Kolmogorov complexity. We treat all aspects of the elementary mathematical theory of Kolmogorov complexity. This body of knowledge may be called algo rithmic complexity theory. The theory of Martin-Lof tests for random ness of finite objects and infinite sequences is inextricably intertwined with the theory of Kolmogorov complexity and is completely treated. We also investigate the statistical properties of finite strings with high Kolmogorov complexity. Both of these topics are eminently useful in the applications part of the book. We also investigate the recursion theoretic properties of Kolmogorov complexity (relations with Godel's incompleteness result), and the Kolmogorov complexity version of infor mation theory, which we may call "algorithmic information theory" or "absolute information theory. " The treatment of algorithmic probability theory in Chapter 4 presup poses Sections 1. 6, 1. 11. 2, and Chapter 3 (at least Sections 3. 1 through 3. 4).

We live in a moment of unprecedented complexity, an era in which change occurs faster than our ability to comprehend it. With "The Moment of Complexity", Mark C. Taylor offers a map for the unfamiliar terrain opening in our midst, unfolding an original philosophy of our time through a remarkable synthesis of science and culture. According to Taylor, complexity is not just a breakthrough scientific concept but the defining quality of the post-Cold War era. The flux of digital currents swirling around us, he argues, has created a new network culture with its own distinctive logic and dynamic.

Shed Revenue-Draining Complexity Costs by Thirty Percent! “This is an ambitious book packed with insight and fresh thinking. Separating good from bad complexity costs is a critical task facing companies today, and the authors provide a compelling roadmap for solving the problem.” Michael B. McCallister, President and CEO, Humana Inc. “Waging War on Complexity Costs examines an incredibly important and often overlooked aspect of business and organizations in general—regulators and government officials should read this book and take notice. Complexity dramatically increases costs and risk of failure. It is like a cancer that eats away at efficiency and profitability.” Andy Beal, Chairman and CEO, Beal Bank “This is by far the best and most useful explanation of how to address complexity in a business. Waging War on Complexity Costs frames the issue in a way that companies can finally tackle the problem—this book delivers.” Ahmad R. Chatila, CEO, MEMC Electronic Materials Inc. “This is the first book that really targets organizational complexity in a compelling way, making this a must-read for any organization that is looking to distance itself from the competition. After years of cost-cutting, many companies are realizing that they still don’t have a discernable cost advantage. This book provides the platform to achieve just that, by attacking the complexity that bogs them down.” Tom DiDonato, EVP Human Resources, American Eagle Outfitters, Inc. About the Book: Complexity costs are the single biggest determinant of your company’s cost competitiveness. For the past two decades the pursuit of growth has created massive complexity in processes, product portfolios, and organizations, adding costs that companies can ill afford. The only good news is that your competitors may be carrying as much complexity as you are. Learn how to eliminate this complexity, and you can create a tremendous cost advantage over your competition. In Waging War on Complexity Costs, Stephen Wilson and Andrei Perumal deliver a powerful and practical approach for reclaiming your cost advantage. This executive-level resource presents a wealth of insight and new research to definitively answer key questions such as: How can I quantify the cost of complexity without getting lost in a sea of data? Where are the biggest opportunities for reducing product, process, and organizational complexity, and how can I cut through the interdependencies that trap these costs? How can I see results quickly by taking targeted actions against key levers? How do I keep complexity costs at bay? It is not enough to attack bloated product portfolios. Substantive cost improvements require addressing the complexity in the underlying processes and organizational structures. Waging War on Complexity Costs provides a wealth of relevant case studies with examples from Kraft, Tesco, Fiat, and the U.S. Navy and highlights specific strategies for reducing costs by 15-30% in significant portions of your business. Tomorrow’s consumers are emerging as wellinformed customers who know what they want and the price they’re willing to pay for it. Complexity not only drives costs; it creates a barrier between you and the customer. Declare a war on complexity costs and prepare for profitable growth.
