Автор: Oded Goldreich Название: Computational complexity ISBN: 052188473X ISBN13(EAN): 9780521884730 Издательство: Cambridge Academ Цена: 4996 р. Наличие на складе: Нет в наличии. Описание: Complexity theory is a central field of the theoretical foundations of computer science. It is concerned with the general study of the intrinsic complexity of computational tasks; that is, it addresses the question of what can be achieved within limited time (and/or with other limited natural computational resources). This book offers a conceptual perspective on complexity theory. It is intended to serve as an introduction for advanced undergraduate and graduate students, either as a textbook or for selfstudy. The book will also be useful to experts, since it provides expositions of the various subareas of complexity theory such as hardness amplification, pseudorandomness and probabilistic proof systems. In each case, the author starts by posing the intuitive questions that are addressed by the subarea and then discusses the choices made in the actual formulation of these questions, the approaches that lead to the answers, and the ideas that are embedded in these answers.

Автор: Langtangen Название: Python Scripting for Computational Science ISBN: 3540294155 ISBN13(EAN): 9783540294153 Издательство: Springer Цена: 3847 р. Наличие на складе: Нет в наличии. Описание: The goal of this book is to teach computational scientists how to develop tailored, flexible, and humanefficient working environments built from small programs
(scripts) written in the easytolearn, highlevel language Python. The focus is on examples and applications of relevance to computational scientists: gluing existing applications and
tools, e.g. for automating simulation, data analysis, and visualization; steering simulations and computational experiments; equipping old programs with graphical user interfaces; making
computational Web applications; and creating interactive interfaces with a Maple/Matlablike syntax to numerical applications in C/C++ or Fortran.
In short, scripting with
Python makes you much more productive, increases the reliability of your scientific work and lets you have more fun  on Unix, Windows and Macintosh. All the tools and examples in
this book are open source codes. The second edition features new material, reorganization of text, improved examples and tools, updated information, and correction of errors.

Автор: Bondeson, Anders Название: Computational Electromagnetics ISBN: 0387261583 ISBN13(EAN): 9780387261584 Издательство: Springer Цена: 4232 р. Наличие на складе: Невозможна поставка. Описание: Computational electromagnetics is a young and growing discipline, expanding as a result of the steadily increasing demand for software for the design and analysis of electrical devices. This book introduces three of the most popular numerical methods for simulating electromagnetic fields: the finite difference method, the finite element method and the method of moments. In particular it focuses on how these methods are used to obtain valid approximations to the solutions of Maxwell's equations, using, for example, "staggered grids" and "edge elements." The main goal of the book is to make the reader aware of different sources of errors in numerical computations, and also to provide the tools for assessing the accuracy of numerical methods and their solutions. To reach this goal, convergence analysis, extrapolation, von Neumann stability analysis, and dispersion analysis are introduced and used frequently throughout the book. Another major goal of the book is to provide students with enough practical understanding of the methods so they are able to write simple programs on their own. To achieve this, the book contains several MATLAB programs and detailed description of practical issues such as assembly of finite element matrices and handling of unstructured meshes. Finally, the book aims at making the students wellaware of the strengths and weaknesses of the different methods, so they can decide which method is best for each problem. The intended audience of this text consists of undergraduate and beginning graduate students with basic knowledge of electromagnetic field theory, numerical analysis, and MATLABprogramming. Купить

Автор: Gentle James E. Название: Elements of Computational Statistics ISBN: 0387954899 ISBN13(EAN): 9780387954899 Издательство: Springer Цена: 5926 р. Наличие на складе: Нет в наличии. Описание: Computationally intensive methods have become widely used both for statistical inference and for exploratory analyses of data. The methods of computational statistics involve resampling, partitioning, and multiple transformations of a dataset. They may also make use of randomly generated artificial data. Implementation of these methods often requires advanced techniques in numerical analysis, so there is a close connection between computational statistics and statistical computing. This book describes techniques used in computational statistics, and addresses some areas of application of computationally intensive methods, such as density estimation, identification of structure in data, and model building. Although methods of statistical computing are not emphasized in this book, numerical techniques for transformations, for function approximation, and for optimization are explained in the context of the statistical methods. The book includes exercises, some with solutions. The book can be used as a text or supplementary text for various courses in modern statistics at the advanced undergraduate or graduate level, and it can also be used as a reference for statisticians who use computationallyintensive methods of analysis. Although some familiarity with probability and statistics is assumed, the book reviews basic methods of inference, and so is largely selfcontained. James Gentle is University Professor of Computational Statistics at George Mason University. He is a Fellow of the American Statistical Association and a member of the International Statistical Institute. He has held several national offices in the American Statistical Association and has served as associate editor for journals of the ASA as well as for other journals in statistics and computing. He is the author of Random Number Generation and Monte Carlo Methods and Numerical Linear Algebra for Statistical Applications. Купить
 

Автор: Derksen Harm, Kemper Gregor Название: Computational Invariant Theory ISBN: 3540434763 ISBN13(EAN): 9783540434764 Издательство: Springer Цена: 7466 р. Наличие на складе: Нет в наличии. Описание: Throughout the history of invariant theory, computational methods have always been at the center of attention. This book, the first volume of the new subseries on "Invariant Theory and Algebraic Transformation Groups", provides a comprehensive and uptodate overview of the algorithmic aspects of invariant theory. Special features are an introductory chapter on GrГ¶bner basis methods and a chapter on applications, covering fields as disparate as graph theory, coding theory, dynamical systems, and computer vision. Both authors have made significant contributions to the theory and practice of algorithmic invariant theory. Numerous illustrative examples and a careful selection of proofs make the book accessible to nonspecialists.The book will be very useful to postgraduate students as well as researchers in geometry, computer algebra, and, of course, invariant theory.

Автор: Comon Hubert, Marche Claude, Treinen Ralf Название: Constraints in Computational Logics. Theory and Applications / International Summer School, CCL`99 GifsurYvette, France, September 58, 1999 Revised Lectures ISBN: 3540419500 ISBN13(EAN): 9783540419501 Издательство: Springer Цена: 4078 р. Наличие на складе: Нет в наличии. Описание: Constraints provide a declarative way of representing infinite sets of data. They are well suited for combining different logical or programming paradigms as has been known for constraint logic programming since the 1980s and more recently for functional programming. The use of constraints in automated deduction is more recent and has proved to be very successful, moving the control from the metalevel to the constraints, which are now firstclass objects.This monographlike book presents six thoroughly reviewed and revised lectures given by leading researchers at the summer school organized by the ESPRIT CCL Working Group in GifsurYvette, France, in September 1999. The book offers coherently written chapters on constraints and constraint solving, constraint solving on terms, combining constraint solving, constraints and theorem proving, functional and constraint logic programming, and building industrial applications.
