Pattern Recognition on Oriented Matroids covers a range of
innovative problems in combinatorics, poset and graph theories,
optimization, and number theory that constitute a far-reaching
extension of the arsenal of committee methods in pattern
recognition. The groundwork for the modern committee theory was
laid in the mid-1960s, when it was shown that the familiar notion
of solution to a feasible system of linear inequalities has
ingenious analogues which can serve as collective solutions to
infeasible systems. A hierarchy of dialects in the language of
mathematics, for instance, open cones in the context of linear
inequality systems, regions of hyperplane arrangements, and maximal
covectors (or topes) of oriented matroids, provides an excellent
opportunity to take a fresh look at the infeasible system of
homogeneous strict linear inequalities - the standard working model
for the contradictory two-class pattern recognition problem in its
geometric setting. The universal language of oriented matroid
theory considerably simplifies a structural and enumerative
analysis of applied aspects of the infeasibility phenomenon. The
present book is devoted to several selected topics in the emerging
theory of pattern recognition on oriented matroids: the questions
of existence and applicability of matroidal generalizations of
committee decision rules and related graph-theoretic constructions
to oriented matroids with very weak restrictions on their
structural properties; a study (in which, in particular,
interesting subsequences of the Farey sequence appear naturally) of
the hierarchy of the corresponding tope committees; a description
of the three-tope committees that are the most attractive
approximation to the notion of solution to an infeasible system of
linear constraints; an application of convexity in oriented
matroids as well as blocker constructions in combinatorial
optimization and in poset theory to enumerative problems on tope
committees; an attempt to clarify how elementary changes
(one-element reorientations) in an oriented matroid affect the
family of its tope committees; a discrete Fourier analysis of the
important family of critical tope committees through rank and
distance relations in the tope poset and the tope graph; the
characterization of a key combinatorial role played by the
symmetric cycles in hypercube graphs. Contents Oriented Matroids,

The best selling 'Algorithmics' presents the most important,
concepts, methods and results that are fundamental to the science
of computing. It starts by introducing the basic ideas of
algorithms, including their structures and methods of data
manipulation. It then goes on to demonstrate how to design accurate
and efficient algorithms, and discusses their inherent limitations.
As the author himself says in the preface to the book; 'This book
attempts to present a readable account of some of the most
important and basic topics of computer science, stressing the
fundamental and robust nature of the science in a form that is
virtually independent of the details of specific computers,
languages and formalisms'.
Hardbound. This book deals with numerical methods for solving large
sparse linear systems of equations, particularly those arising from
the discretization of partial differential equations. It covers
both direct and iterative methods. Direct methods which are
considered are variants of Gaussian elimination and fast solvers
for separable partial differential equations in rectangular
domains. The book reviews the classical iterative methods like
Jacobi, Gauss-Seidel and alternating directions algorithms. A
particular emphasis is put on the conjugate gradient as well as
conjugate gradient -like methods for non symmetric problems. Most
efficient preconditioners used to speed up convergence are studied.
A chapter is devoted to the multigrid method and the book ends with
domain decomposition algorithms that are well suited for solving
linear systems on parallel computers.
This book presents fundamental new techniques for understanding and
processing geospatial data. These "spatial gems" articulate and
highlight insightful ideas that often remain unstated in graduate
textbooks, and which are not the focus of research papers. They
teach us how to do something useful with spatial data, in the form
of algorithms, code, or equations. Unlike a research paper, Spatial
Gems, Volume 1 does not focus on "Look what we have done!" but
rather shows "Look what YOU can do!" With contributions from
researchers at the forefront of the field, this volume occupies a
unique position in the literature by serving graduate students,
professional researchers, professors, and computer developers in
the field alike.
In recent years Genetic Algorithms (GA) and Artificial Neural
Networks (ANN) have progressively increased in importance amongst
the techniques routinely used in chemometrics. This book contains
contributions from experts in the field is divided in two sections
(GA and ANN). In each part, tutorial chapters are included in which
the theoretical bases of each technique are expertly (but simply)
described. These are followed by application chapters in which
special emphasis will be given to the advantages of the application
of GA or ANN to that specific problem, compared to classical
techniques, and to the risks connected with its misuse.
This book is of use to all those who are using or are interested in
GA and ANN. Beginners can focus their attentions on the tutorials,
whilst the most advanced readers will be more interested in looking
at the applications of the techniques. It is also suitable as a
reference book for students.
- Subject matter is steadily increasing in importance
- Comparison of Genetic Algorithms (GA) and Artificial Neural
Networks (ANN) with the classical techniques
- Suitable for both beginners and advanced researchers
Throughout time, scientists have looked to nature in order to

Optimization is presented in most multivariable calculus courses as
an application of the gradient, and while this treatment makes
sense for a calculus course, there is much more to the theory of
optimization. Optimization problems are generated constantly, and
the theory of optimization has grown and developed in response to
the challenges presented by these problems. This textbook aims to
show readers how optimization is done in practice and help them to
develop an appreciation for the richness of the theory behind the
practice. Exercises, problems (including modeling and computational
problems), and implementations are incorporated throughout the text
to help students learn by doing. Python notes are inserted
strategically to help readers complete computational problems and
implementations. The Basics of Practical Optimization, Second
Edition is intended for undergraduates who have completed
multivariable calculus, as well as anyone interested in
optimization. The book is appropriate for a course that complements
or replaces a standard linear programming course.

Graph theory is a specific concept that has numerous applications
throughout many industries. Despite the advancement of this
technique, graph theory can still yield ambiguous and imprecise
results. In order to cut down on these indeterminate factors,
neutrosophic logic has emerged as an applicable solution that is
gaining significant attention in solving many real-life
decision-making problems that involve uncertainty, impreciseness,
vagueness, incompleteness, inconsistency, and indeterminacy.
However, empirical research on this specific graph set is lacking.
Neutrosophic Graph Theory and Algorithms is a collection of
innovative research on the methods and applications of neutrosophic
sets and logic within various fields including systems analysis,
economics, and transportation. While highlighting topics including
linear programming, decision-making methods, and homomorphism, this
book is ideally designed for programmers, researchers, data
scientists, mathematicians, designers, educators, researchers,
academicians, and students seeking current research on the various
methods and applications of graph theory.

Digital Intermediation offers a new framework for understanding
content creation and distribution across automated media platforms
- a new mediatisation process. The book draws on empirical and
theoretical research to carefully identify and describe a number of
unseen digital infrastructures that contribute to a predictive
media production process through technologies, institutions and
automation. Field data is drawn from several international sites,
including Los Angeles, San Francisco, Portland, London, Amsterdam,
Munich, Berlin, Hamburg, Sydney and Cartagena. By highlighting an
increasingly automated content production and distribution process,
the book responds to a number of regulatory debates on the societal
impact of social media platforms. It highlights emerging areas of
key importance that shape the production and distribution of social
media content, including micro-platformization and digital first
personalities. The book explains how technologies, institutions and
automation are used within agencies to increase exposure for the
talent they manage, while providing inside access to the processes
and requirements of producers who create content for platform
algorithms. Finally, it outlines user agency as a strategy for
those who seek diversity in the information they access on
automated social media content distribution platforms. The findings
in this book provide key recommendations for policymakers working
within digital media platforms, and will be invaluable reading for
students and academics interested in automated media environments.
In recent years, popular media have inundated audiences with
sensationalised headlines recounting data breaches, new forms of
surveillance and other dangers of our digital age. Despite their
regularity, such accounts treat each case as unprecedented and
unique. This book proposes a radical rethinking of the history,
present and future of our relations with the digital, spatial
technologies that increasingly mediate our everyday lives. From
smartphones to surveillance cameras, to navigational satellites,
these new technologies offer visions of integrated, smooth and
efficient societies, even as they directly conflict with the ways
users experience them. Recognising the potential for both control
and liberation, the authors argue against both acquiescence to and
rejection of these technologies. Through intentional use of the
very systems that monitor them, activists from Charlottesville to
Hong Kong are subverting, resisting and repurposing geographic
technologies. Using examples as varied as writings on the first
telephones to the experiences of a feminist collective for migrant
women in Spain, the authors present a revolution of everyday
technologies. In the face of the seemingly inevitable dominance of
corporate interests, these technologies allow us to create new
spaces of affinity, and a new politics of change.
A best-seller in its French edition, the construction of this book
is original and its success in the French market demonstrates its
appeal. It is based on three principles: 1. An organization of the
chapters by families of algorithms : exhaustive search, divide and
conquer, etc. At the contrary, there is no chapter only devoted to
a systematic exposure of, say, algorithms on strings. Some of these
will be found in different chapters. 2. For each family of
algorithms, an introduction is given to the mathematical principles
and the issues of a rigorous design, with one or two pedagogical
examples. 3. For its most part, the book details 150 problems,
spanning on seven families of algorithms. For each problem, a
precise and progressive statement is given. More important, a
complete solution is detailed, with respect to the design
principles that have been presented ; often, some classical errors
are pointed at. Roughly speaking, two thirds of the book are
devoted to the detailed rational construction of the solutions.
The contributions by leading experts in this book focus on a
variety of topics of current interest related to information-based
complexity, ranging from function approximation, numerical
integration, numerical methods for the sphere, and algorithms with
random information, to Bayesian probabilistic numerical methods and
numerical methods for stochastic differential equations.
This book is designed as a reference book and presents a systematic
approach to analyze evolutionary and nature-inspired
population-based search algorithms. Beginning with an introduction
to optimization methods and algorithms and various enzymes, the
book then moves on to provide a unified framework of process
optimization for enzymes with various algorithms. The book presents
current research on various applications of machine learning and
discusses optimization techniques to solve real-life problems. The
book compiles the different machine learning models for
optimization of process parameters for production of industrially
important enzymes. The production and optimization of various
enzymes produced by different microorganisms are elaborated in the
book It discusses the optimization methods that help minimize the
error in developing patterns and classifications, which further
helps improve prediction and decision-making Covers the
best-performing methods and approaches for optimization sustainable
enzymes production with AI integration in a real-time environment
Featuring valuable insights, the book helps readers explore new
avenues leading towards multidisciplinary research discussions The
book is aimed primarily at advanced undergraduates and graduates
studying machine learning, data science and industrial
biotechnology. Researchers and professionals will also find this
book useful.
The TransNav 2011 Symposium held at the Gdynia Maritime University,
Poland in June 2011 has brought together a wide range of
participants from all over the world. The program has offered a
variety of contributions, allowing to look at many aspects of the
navigational safety from various different points of view. Topics
presented and discussed at the Symposium were: navigation, safety
at sea, sea transportation, education of navigators and
simulator-based training, sea traffic engineering, ship's
manoeuvrability, integrated systems, electronic charts systems,
satellite, radio-navigation and anti-collision systems and many
others. This book is part of a series of six volumes and provides
an overview of Methods and Algorithms in Navigation and is
addressed to scientists and professionals involved in research and
development of navigation, safety of navigation and sea
transportation.
Designed for a proof-based course on linear algebra, this rigorous
and concise textbook intentionally introduces vector spaces, inner
products, and vector and matrix norms before Gaussian elimination
and eigenvalues so students can quickly discover the singular value
decomposition (SVD)-arguably the most enlightening and useful of
all matrix factorizations. Gaussian elimination is then introduced
after the SVD and the four fundamental subspaces and is presented
in the context of vector spaces rather than as a computational
recipe. This allows the authors to use linear independence,
spanning sets and bases, and the four fundamental subspaces to
explain and exploit Gaussian elimination and the LU factorization,
as well as the solution of overdetermined linear systems in the
least squares sense and eigenvalues and eigenvectors. This unique
textbook also includes examples and problems focused on concepts
rather than the mechanics of linear algebra. The problems at the
end of each chapter and in an associated website encourage readers
to explore how to use the notions introduced in the chapter in a
variety of ways. Additional problems, quizzes, and exams will be
posted on an accompanying website and updated regularly. The Less
Is More Linear Algebra of Vector Spaces and Matrices is for
students and researchers interested in learning linear algebra who
have the mathematical maturity to appreciate abstract concepts that
generalize intuitive ideas. The early introduction of the SVD makes
the book particularly useful for those interested in using linear
algebra in applications such as scientific computing and data
science. It is appropriate for a first proof-based course in linear
algebra.
