Download or read book Feedback Arc Set written by Robert Kudelić and published by Springer Nature. This book was released on 2022-10-10 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main aim of the book is to give a review of all relevant information regarding a well-known and important problem of Feedback Arc Set (FAS). This review naturally also includes a history of the problem, as well as specific algorithms. To this point such a work does not exist: There are sources where one can find incomplete and perhaps untrustworthy information. With this book, information about FAS can be found easily in one place: formulation, description, theoretical background, applications, algorithms etc. Such a compendium will be of help to people involved in research, but also to people that want to quickly acquaint themselves with the problem and need reliable information. Thus research, professional work and learning can proceed in a more streamlined and faster way.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive analysis of the most important topics in parallel computation. It is written so that it may be used as a self-study guide to the field, and researchers in parallel computing will find it a useful reference for many years to come. The first half of the book consists of an introduction to many fundamental issues in parallel computing. The second half provides lists of P-complete- and open problems. These lists will have lasting value to researchers in both industry and academia. The lists of problems, with their corresponding remarks, the thorough index, and the hundreds of references add to the exceptional value of this resource. While the exciting field of parallel computation continues to expand rapidly, this book serves as a guide to research done through 1994 and also describes the fundamental concepts that new workers will need to know in coming years. It is intended for anyone interested in parallel computing, including senior level undergraduate students, graduate students, faculty, and people in industry. As an essential reference, the book will be needed in all academic libraries.
Download or read book Handbook of Combinatorial Optimization written by Ding-Zhu Du and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combinatorial (or discrete) optimization is one of the most active fields in the interface of operations research, computer science, and applied math ematics. Combinatorial optimization problems arise in various applications, including communications network design, VLSI design, machine vision, air line crew scheduling, corporate planning, computer-aided design and man ufacturing, database query design, cellular telephone frequency assignment, constraint directed reasoning, and computational biology. Furthermore, combinatorial optimization problems occur in many diverse areas such as linear and integer programming, graph theory, artificial intelligence, and number theory. All these problems, when formulated mathematically as the minimization or maximization of a certain function defined on some domain, have a commonality of discreteness. Historically, combinatorial optimization starts with linear programming. Linear programming has an entire range of important applications including production planning and distribution, personnel assignment, finance, alloca tion of economic resources, circuit simulation, and control systems. Leonid Kantorovich and Tjalling Koopmans received the Nobel Prize (1975) for their work on the optimal allocation of resources. Two important discover ies, the ellipsoid method (1979) and interior point approaches (1984) both provide polynomial time algorithms for linear programming. These algo rithms have had a profound effect in combinatorial optimization. Many polynomial-time solvable combinatorial optimization problems are special cases of linear programming (e.g. matching and maximum flow). In addi tion, linear programming relaxations are often the basis for many approxi mation algorithms for solving NP-hard problems (e.g. dual heuristics).

Download or read book Concurrent Computations written by Stuart K. Tewksbury and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 719 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1987 Princeton Workshop on Algorithm, Architecture and Technology Issues for Models of Concurrent Computation was organized as an interdisciplinary work shop emphasizing current research directions toward concurrent computing systems. With participants from several different fields of specialization, the workshop cov ered a wide variety of topics, though by no means a complete cross section of issues in this rapidly moving field. The papers included in this book were prepared for the workshop and, taken together, provide a view of the broad range of issues and alternative directions being explored. To organize the various papers, the book has been divided into five parts. Part I considers new technology directions. Part II emphasizes underlying theoretical issues. Communication issues, which are ad dressed in the majority of papers, are specifically highlighted in Part III. Part IV includes papers stressing the fault tolerance and reliability of systems. Finally, Part V includes systems-oriented papers, where the system ranges from VLSI circuits through powerful parallel computers. Much of the initial planning of the workshop was completed through an informal AT&T Bell Laboratories group consisting of Mehdi Hatamian, Vijay Kumar, Adri aan Ligtenberg, Sailesh Rao, P. Subrahmanyam and myself. We are grateful to Stuart Schwartz, both for the support of Princeton University and for his orga nizing local arrangements for the workshop, and to the members of the organizing committee, whose recommendations for participants and discussion topics were par ticularly helpful.

Download or read book The Quadratic Assignment Problem written by E. Cela and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quadratic assignment problem (QAP) was introduced in 1957 by Koopmans and Beckmann to model a plant location problem. Since then the QAP has been object of numerous investigations by mathematicians, computers scientists, ope- tions researchers and practitioners. Nowadays the QAP is widely considered as a classical combinatorial optimization problem which is (still) attractive from many points of view. In our opinion there are at last three main reasons which make the QAP a popular problem in combinatorial optimization. First, the number of re- life problems which are mathematically modeled by QAPs has been continuously increasing and the variety of the fields they belong to is astonishing. To recall just a restricted number among the applications of the QAP let us mention placement problems, scheduling, manufacturing, VLSI design, statistical data analysis, and parallel and distributed computing. Secondly, a number of other well known c- binatorial optimization problems can be formulated as QAPs. Typical examples are the traveling salesman problem and a large number of optimization problems in graphs such as the maximum clique problem, the graph partitioning problem and the minimum feedback arc set problem. Finally, from a computational point of view the QAP is a very difficult problem. The QAP is not only NP-hard and - hard to approximate, but it is also practically intractable: it is generally considered as impossible to solve (to optimality) QAP instances of size larger than 20 within reasonable time limits.
Download or read book Fast and Processor Efficient Parallel Algorithms for Reducible Flow Graphs written by Vijaya Ramachandran and published by . This book was released on 1988 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents parallel NC algorithms for recognizing reducible flow graphs, and for finding dominators, minimum feedback vertex sets, and a depth first search numbering in an rfg. All of these algorithms run in polylog parallel time using M (n) processors, where M (n) is the number of processors needed to multiply two nxn matrices in polylog time; this is the best processor bound currently known for polylog-time parallel algorithms for directed graphs. It is shown that finding a minimum feedback vertex is in vertex-weighted rfg's or finding a minimum feedback arc set in arc-weighted rfg's is complete. For arc or vertex weights in unary, we present RNC algorithms for these problems and show that these problems are in NC if and only if the problem of finding a maximum matching is in NC. Keywords: Parallel computations. (KR).
