Available in PDF, EPUB and Kindle. Book excerpt: Der erfolgreiche Einsatz von Rechnern bei der Lösung von Problemen in fast allen Lebensbereichen beruht u.a. auf der technologischen Entwicklung, die zu schnelle ren Rechnern mit größerem Speicher führte, auf der größeren Benutzerfreundlich keit der Rechner und auf effizienteren Algorithmen zur Lösung der betrachteten Probleme. Dieses Buch befaßt sich mit dem Entwurf effizienter Algorithmen für grundlegende Probleme, die häufig als Teilprobleme in komplexeren Problemen auftreten. Während auf der unteren Ebene der Hardware von Rechnern, also in Schaltkreisen, Schaltwerken und VLSI-Chips, schon immer mit einem hohen Grad an Parallelität gearbeitet wurde, konnte auf höherer Ebene lange Zeit nur sequentiell gerechnet werden. Dies ändert sich nun durch die Entwicklung von Rechnern mit immer mehr Prozessoren. Das Buch legt daher einen Schwerpunkt auf Algorithmen, die gleich zeitig bezüglich paralleler Rechenzeit und Hardwaregröße (bei Hardwarelösungen) bzw. bezüglich paralleler Rechenzeit, Zahl der benutzten Prozessoren und Spei cherplatz (bei Softwarelösungen) effizient sind. Es werden effiziente Algorithmen für den Entwurf optimaler P LA's diskutiert. Danach werden die grundlegenden arithmetischen Funktionen Addition, Subtrak tion, Multiplikation und Division, die symmetrischen Funktionen, die auch als Zählfunktionen bezeichnet werden können, und Speicherzugriffsfunktionen behan delt. In diesem Teil des Buches werden vor allem Hardwarelösungen präsentiert. Für das Rechnen mit Matrizen, einfache Probleme auf Graphen, Sortierprobleme und Probleme der Elementaren Zahlentheorie werden effiziente Softwarelösungen vorgestellt. Das Buch enthält außerdem allgemeine Methoden der automatischen Parallelisierung sequentieller Algorithmen, Reduktionskonzepte zum Vergleich der Komplexität der behandelten Probleme und effiziente Simulationen zwischen den benutzten Rechenmodellen.

Book Synopsis Multicriteria Decision Making by : Tomas Gal
Download or read book Multicriteria Decision Making written by Tomas Gal and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a practical level, mathematical programming under multiple objectives has emerged as a powerful tool to assist in the process of searching for decisions which best satisfy a multitude of conflicting objectives, and there are a number of distinct methodologies for multicriteria decision-making problems that exist. These methodologies can be categorized in a variety of ways, such as form of model (e.g. linear, non-linear, stochastic), characteristics of the decision space (e.g. finite or infinite), or solution process (e.g. prior specification of preferences or interactive). Scientists from a variety of disciplines (mathematics, economics and psychology) have contributed to the development of the field of Multicriteria Decision Making (MCDM) (or Multicriteria Decision Analysis (MCDA), Multiattribute Decision Making (MADM), Multiobjective Decision Making (MODM), etc.) over the past 30 years, helping to establish MCDM as an important part of management science. MCDM has become a central component of studies in management science, economics and industrial engineering in many universities worldwide. Multicriteria Decision Making: Advances in MCDM Models, Algorithms, Theory and Applications aims to bring together `state-of-the-art' reviews and the most recent advances by leading experts on the fundamental theories, methodologies and applications of MCDM. This is aimed at graduate students and researchers in mathematics, economics, management and engineering, as well as at practicing management scientists who wish to better understand the principles of this new and fast developing field.

Book Synopsis Steiner Minimal Trees by : Dietmar Cieslik
Download or read book Steiner Minimal Trees written by Dietmar Cieslik and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of "Shortest Connectivity", which is discussed here, has a long and convoluted history. Many scientists from many fields as well as laymen have stepped on its stage. Usually, the problem is known as Steiner's Problem and it can be described more precisely in the following way: Given a finite set of points in a metric space, search for a network that connects these points with the shortest possible length. This shortest network must be a tree and is called a Steiner Minimal Tree (SMT). It may contain vertices different from the points which are to be connected. Such points are called Steiner points. Steiner's Problem seems disarmingly simple, but it is rich with possibilities and difficulties, even in the simplest case, the Euclidean plane. This is one of the reasons that an enormous volume of literature has been published, starting in 1 the seventeenth century and continuing until today. The difficulty is that we look for the shortest network overall. Minimum span ning networks have been well-studied and solved eompletely in the case where only the given points must be connected. The novelty of Steiner's Problem is that new points, the Steiner points, may be introduced so that an intercon necting network of all these points will be shorter. This also shows that it is impossible to solve the problem with combinatorial and geometric methods alone.
Book Synopsis Datenstrukturen und effiziente Algorithmen by : Kurt Mehlhorn
Download or read book Datenstrukturen und effiziente Algorithmen written by Kurt Mehlhorn and published by Springer. This book was released on 1988 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Der Entwurf und die Analyse von Datenstrukturen und effizienten Algorithmen hat in den letzten Jahren große Bedeutung erlangt: Algorithmus ist der zentrale Begriff der Informatik und Effizienz bedeutet Geld. Ich habe den Stoff in drei Bände und neun Kapitel gegliedert. Band 1: Sortieren und Suchen (Kapitel I bis ill) Band 2: Graphenalgorithmen und NP-Vollständigkeit (Kapitel IV bis VI) Band 3: Mehrdimensionales Suchen und Algorithmische Geometrie (Kapitel VII und Vill), Algorithmische Paradigmen (Kapitel IX) Die Bände 2 und 3 haben Band 1 als gemeinsame Basis, sind aber voneinander un abhängig. Große Teile dieser Bände können ohne detaillierte Kenntnis von Band 1 gelesen werden; eine Kenntnis der algorithmischen Grundprinzipien, wie sie etwa in Kapitel I oder in vielen anderen Büchern über Datenstrukturen und Algorith men vermittelt werden, genügt. Die spezifischen Voraussetzungen für die Bände 2 und 3 sind in den jeweiligen Vorworten angegeben. In allen drei Bänden stellen wir wichtige effiziente Algorithmen für die grundlegenden Probleme in dem jeweiligen Gebiet vor und analysieren sie. Wir messen dabei Effizienz durch die Laufzeit auf einem realistischen Modell einer Rechenanlage, das wir in Kapitel I einführen. Die meisten der vorgestellten Algorithmen wurden erst in den letzten Jahren gefunden; die Informatik ist ja schließlich eine sehr junge Wissenschaft. Es gibt kaum Sätze in diesem Buch, die älter als 20 Jahre sind, und mindestens die Hälfte des Stoffes ist jünger als 10 Jahre. Ich habe stets versucht, den Leser bis an den Stand der Forschung heranzuführen.

Book Synopsis Intelligent Strategies for Meta Multiple Criteria Decision Making by : Thomas Hanne
Download or read book Intelligent Strategies for Meta Multiple Criteria Decision Making written by Thomas Hanne and published by Springer. This book was released on 2000-12-31 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the "meta-decision problem"--the problem of the numerous MCDM methods that can be applied to a decision problem. It provides two strategies to help the decision-makers select and design an appropriate approach to a complex decision problem. One strategy is to use machine learning to design an MCDM method. The other is based on solving the meta-decision problem interactively by selecting or designing a method suitable to the specific problem. Examples of this approach explain the possibilities of applying the elaborated techniques and their mutual interplay. Specific chapters explain the meta-decision problem, and discuss neural networks, evolutionary learning, combinations of MCDM methods, loops, and applications of loops. c. Book News Inc.

Book Synopsis Branching Programs and Binary Decision Diagrams by : Ingo Wegener
Download or read book Branching Programs and Binary Decision Diagrams written by Ingo Wegener and published by SIAM. This book was released on 2000-01-01 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finite functions (in particular, Boolean functions) play a fundamental role in computer science and discrete mathematics. This book describes representations of Boolean functions that have small size for many important functions and which allow efficient work with the represented functions. The representation size of important and selected functions is estimated, upper and lower bound techniques are studied, efficient algorithms for operations on these representations are presented, and the limits of those techniques are considered. This book is the first comprehensive description of theory and applications. Research areas like complexity theory, efficient algorithms, data structures, and discrete mathematics will benefit from the theory described in this book. The results described within have applications in verification, computer-aided design, model checking, and discrete mathematics. This is the only book to investigate the representation size of Boolean functions and efficient algorithms on these representations.

Available in PDF, EPUB and Kindle. Book excerpt: "This sobering description of many computer-related failures throughout our world deflates the hype and hubris of the industry. Peter Neumann analyzes the failure modes, recommends sequences for prevention and ends his unique book with some broadening reflections on the future." —Ralph Nader, Consumer Advocate This book is much more than a collection of computer mishaps; it is a serious, technically oriented book written by one of the world's leading experts on computer risks. The book summarizes many real events involving computer technologies and the people who depend on those technologies, with widely ranging causes and effects. It considers problems attributable to hardware, software, people, and natural causes. Examples include disasters (such as the Black Hawk helicopter and Iranian Airbus shootdowns, the Exxon Valdez, and various transportation accidents); malicious hacker attacks; outages of telephone systems and computer networks; financial losses; and many other strange happenstances (squirrels downing power grids, and April Fool's Day pranks). Computer-Related Risks addresses problems involving reliability, safety, security, privacy, and human well-being. It includes analyses of why these cases happened and discussions of what might be done to avoid recurrences of similar events. It is readable by technologists as well as by people merely interested in the uses and limits of technology. It is must reading for anyone with even a remote involvement with computers and communications—which today means almost everyone. Computer-Related Risks: Presents comprehensive coverage of many different types of risks Provides an essential system-oriented perspective Shows how technology can affect your life—whether you like it or not!

Available in PDF, EPUB and Kindle. Book excerpt: Actuator saturation is probably the most frequent nonlinearity encountered in control applications. Input saturation leads to controller windup, removable by structural modification during compensator realization and plant windup which calls for additional dynamics. This book presents solutions to the windup prevention problem for stable and unstable single-input-single-output and multiple-input-multiple-output (MIMO) systems.
Book Synopsis Advancing the Discovery of Unique Column Combinations by : Ziawasch Abedjan
Download or read book Advancing the Discovery of Unique Column Combinations written by Ziawasch Abedjan and published by Universitätsverlag Potsdam. This book was released on 2011 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unique column combinations of a relational database table are sets of columns that contain only unique values. Discovering such combinations is a fundamental research problem and has many different data management and knowledge discovery applications. Existing discovery algorithms are either brute force or have a high memory load and can thus be applied only to small datasets or samples. In this paper, the wellknown GORDIAN algorithm and "Apriori-based" algorithms are compared and analyzed for further optimization. We greatly improve the Apriori algorithms through efficient candidate generation and statistics-based pruning methods. A hybrid solution HCAGORDIAN combines the advantages of GORDIAN and our new algorithm HCA, and it significantly outperforms all previous work in many situations.
Book Synopsis High-level Petri Nets by : Kurt Jensen
Download or read book High-level Petri Nets written by Kurt Jensen and published by Springer. This book was released on 1991-07-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-level Petri nets are now widely used in both theoretical analysis and practical modelling of concurrent systems. The main reason for the success of this class of net models is that they make it possible to obtain much more succinct and manageable de scriptions than can be obtained by means of low-level Petri nets-while, on the other hand, they still offer a wide range of analysis methods and tools. The step from low-level nets to high-level nets can be compared to the step from assembly languages to modem programming languages with an elaborated type concept. In low-level nets there is only one kind of token and this means that the state of a place is described by an integer (and in many cases even by a boolean value). In high-level nets each token can carry complex information which, e. g. , may describe the entire state of a process or a data base. Today most practical applications of Petri nets use one of the different kinds of high-level nets. A considerable body of knowledge exists about high-level Petri nets this includes theoretical foundations, analysis methods and many applications. Unfortunately, the papers on high-level Petri nets have been scattered throughout various journals and collections. As a result, much of this knowledge is not readily available to people who may be interested in using high-level nets.
