We all know that our planet is losing its biological diversity at an alarming rate, with frightening implications for our future. But when does an ecosystem hit the breaking point? In this important book, Princeton biologist Simon Levin offers general readers the first look at how the new science of complexity can help to solve our looming ecological crisis. Levin argues that our biosphere is the classic embodiment of what scientists call complex adaptive systems. By exploring how such systems work, we can determine how they might fail: How much loss can an ecosystem bear before it starts to collapse? How resilient are these systems? Do they in fact hover at the edge of chaos? A deeply original work on one of the most pressing issues of our time, Fragile Dominion is a powerful appeal to understand and protect the global commons."

The Foundational Debate Complexity and Constructivity in Mathematics and Physics


Free Download The Foundational Debate: Complexity and Constructivity in Mathematics and Physics By Roland Omnès (auth.), Werner Depauli-Schimanovich, Eckehart Köhler, Friedrich Stadler (eds.)
1995 | 354 Pages | ISBN: 9048146178 | PDF | 14 MB
Constructibility and complexity play central roles in recent research in computer science, mathematics and physics. For example, scientists are investigating the complexity of computer programs, constructive proofs in mathematics and the randomness of physical processes. But there are different approaches to the explication of these concepts. This volume presents important research on the state of this discussion, especially as it refers to quantum mechanics. This `foundational debate’ in computer science, mathematics and physics was already fully developed in 1930 in the Vienna Circle. A special section is devoted to its real founder Hans Hahn, referring to his contribution to the history and philosophy of science. The documentation section presents articles on the early Philipp Frank and on the Vienna Circle in exile. Reviews cover important recent literature on logical empiricism and related topics.

Structural Complexity I


Free Download Structural Complexity I By José Luis Balcázar, Josep Díaz, Joaquim Gabarró
1995 | 222 Pages | ISBN: 3642792375 | PDF | 13 MB
In the six years since the first edition of this book was published, the field of Structural Complexity has grown quite a bit. However, we are keeping this volume at the same basic level that it had in the first edition, and the only new result incorporated as an appendix is the closure under complementation of nondeterministic space classes, which in the previous edition was posed as an open problem. This result was already included in our Volume II, but we feel that due to the basic nature of the result, it belongs to this volume. There are of course other important results obtained during these last six years. However, as they belong to new areas opened in the field they are outside the scope of this fundamental volume. Other changes in this second edition are the update of some Bibliograph ical Remarks and references, correction of many mistakes and typos, and a renumbering of the definitions and results. Experience has shown us that this new numbering is a lot more friendly, and several readers have confirmed this opinion. For the sake of the reader of Volume II, where all references to Volume I follow the old numbering, we have included here a table indicating the new number corresponding to each of the old ones.

Data Complexity in Pattern Recognition


Free Download Data Complexity in Pattern Recognition By Tin Kam Ho, Mitra Basu, Martin Hiu Chung Law (auth.), Mitra Basu PhD, Tin Kam Ho BBA, MS, PhD (eds.)
2006 | 300 Pages | ISBN: 1846281717 | PDF | 6 MB
Machines capable of automatic pattern recognition have many fascinating uses in science and engineering as well as in our daily lives. Algorithms for supervised classification, where one infers a decision boundary from a set of training examples, are at the core of this capability. Tremendous progress has been made in refining such algorithms; yet, automatic learning in many simple tasks in daily life still appears to be far from reach.This book takes a close view of data complexity and its role in shaping the theories and techniques in different disciplines and asks:* What is missing from current classification techniques?* When the automatic classifiers are not perfect, is it a deficiency of the algorithms by design, or is it a difficulty intrinsic to the classification task? * How do we know whether we have exploited to the fullest extent the knowledge embedded in the training data? Data Complexity in Pattern Recognition is unique in its comprehensive coverage and multidisciplinary approach from various methodological and practical perspectives. Researchers and practitioners alike will find this book an insightful reference to learn about the current status of available techniques as well as application areas.

Simulating Social Complexity A Handbook


Free Download Simulating Social Complexity: A Handbook By Bruce Edmonds, Ruth Meyer (auth.), Bruce Edmonds, Ruth Meyer (eds.)
2013 | 754 Pages | ISBN: 3540938125 | PDF | 8 MB
Social systems are among the most complex known. This poses particular problems for those who wish to understand them. The complexity often makes analytic approaches infeasible and natural language approaches inadequate for relating intricate cause and effect. However, individual- and agent-based computational approaches hold out the possibility of new and deeper understanding of such systems. Simulating Social Complexity examines all aspects of using agent- or individual-based simulation. This approach represents systems as individual elements having each their own set of differing states and internal processes. The interactions between elements in the simulation represent interactions in the target systems. What makes these elements "social" is that they are usefully interpretable as interacting elements of an observed society. In this, the focus is on human society, but can be extended to include social animals or artificial agents where such work enhances our understanding of human society. The phenomena of interest then result (emerge) from the dynamics of the interaction of social actors in an essential way and are usually not easily simplifiable by, for example, considering only representative actors. The introduction of accessible agent-based modelling allows the representation of social complexity in a more natural and direct manner than previous techniques. In particular, it is no longer necessary to distort a model with the introduction of overly strong assumptions simply in order to obtain analytic tractability. This makes agent-based modelling relatively accessible to a range of scientists. The outcomes of such models can be displayed and animated in ways that also make them more interpretable by experts and stakeholders. This handbook is intended to help in the process of maturation of this new field. It brings together, through the collaborative effort of many leading researchers, summaries of the best thinking and practice in this area and constitutes a reference point for standards against which future methodological advances are judged. This book will help those entering into the field to avoid "reinventing the wheel" each time, but it will also help those already in the field by providing accessible overviews of current thought. The material is divided into four sections: Introductory, Methodology, Mechanisms, and Applications. Each chapter starts with a very brief section called ‘Why read this chapter?’ followed by an abstract, which summarizes the content of the chapter. Each chapter also ends with a section of ‘Further Reading’ briefly describing three to eight items that a newcomer might read next.

Chaos and Complexity in Nonlinear Electronic Circuits


Free Download Maciej J Ogorzalek, "Chaos and Complexity in Nonlinear Electronic Circuits"
English | ISBN: 9810228732 | | 276 pages | PDF | 14 MB
The basic procedures for designing and analysing electronic systems are based largely on the assumptions of linear behavior of the system. Nonlinearities inherent in all real applications very often cause unexpected and even strange behavior. This book presents an electronic engineer’s perspective on chaos and complex behavior. It starts from basic mathematical notions which enable understanding of the observed phenomena, and guides the reader through the methodology and tools used in the laboratory and numerical experiments to interpretation and explanation of basic mechanisms. On typical circuit examples, it shows how the theoretical and empirical developments can be used in practice. Attention is drawn to applications of chaotic circuits as noise generators and the possible use of synchronized chaotic systems in information transmission and encryption. Chaos control is considered as a new, emerging area where electronic equipment and chaos theory could turn vital in biomedical and engineering issues.
