    Computability and Complexity

    From a Programming Perspective

    Neil Deaton Jones

    Computability and complexity theory should be of central concern to practitioners as well as theorists. Unfortunately, however, the field is known for its impenetrability. Neil Jones's goal as an educator and author is to build a bridge between computability and complexity theory and other areas of computer science, especially programming. In a shift away from the Turing machine- and Gödel number-oriented classical approaches, Jones uses concepts familiar from programming languages to make computability and complexity more accessible to computer scientists and more applicable to practical programming problems.

    According to Jones, the fields of computability and complexity theory, as well as programming languages and semantics, have a great deal to offer each other. Computability and complexity theory have a breadth, depth, and generality not often seen in programming languages. The programming language community, meanwhile, has a firm grasp of algorithm design, presentation, and implementation. In addition, programming languages sometimes provide computational models that are more realistic in certain crucial aspects than traditional models.

    New results in the book include a proof that constant time factors do matter for its programming-oriented model of computation. (In contrast, Turing machines have a counterintuitive "constant speedup" property: that almost any program can be made to run faster, by any amount. Its proof involves techniques irrelevant to practice.) Further results include simple characterizations in programming terms of the central complexity classes PTIME and LOGSPACE, and a new approach to complete problems for NLOGSPACE, PTIME, NPTIME, and PSPACE, uniformly based on Boolean programs.

    Selling Public Enterprises

    A Cost-Benefit Methodology

    Leroy P. Jones, Pankaj Tandon, and Ingo Vogelsang

    Much has been written about the current trend toward privatization of public enterprises. Selling Public Enterprises is the first book, however, to use economic logic to develop a quantitative approach to making divestiture decisions. Using the standard tools of applied microeconomics, the authors propose a method of valuing state-owned firms both before and after divestiture by the government. Their valuation method offers significant advantages over those commonly in use (such as book value of assets) and can provide governments with a reliable means of evaluating the costs and benefits of reforming state-owned enterprise policies and procedures. Selling Public Enterprises focuses on the pivotal questions of whether the enterprise should be sold, to whom should it be sold, and at what price. It identifies the social value of the enterprise under continued government operation, the social value under private operation, and the private value under private operation as being critical in determining the answers to these questions. In each case "social value" indicates the economic promise of such a venture to both households and firms of the country involved.The authors take up such topics as shadow pricing, the basic framework of welfare aggregation, the valuation of public income, private income and investment income, base flows and stocks, and the effect of sale prices on public and private values. They discuss the possibility of synergies and strategic behavior and present both a valuation algorithm and a sensitivity analysis. In the concluding chapters they address distributional realities and describe various dimensions of divestiture policy such as lifting constraints on enterprise behavior, improving the net benefit of divestiture, and coping with political constraints.

  • HANDEY

    HANDEY

    A Robot Task Planner

    Joseph L. Jones, Tomás Lozano-Pérez, Emmanuel Mazer, and Patrick A. O'Donnell

    HANDEY is a task-level robot system that requires only a geometric description of a pick-and-place task rather than the specific robot motions necessary to carry out the task. The system-building process this book describes is an important step toward eliminating the current programming bottleneck that is keeping robots from fulfilling their scientific and economic potential. The HANDEY system, the state-of-the art technologies for developing it, and the problems encountered are clearly presented, aided by numerous marginal illustrations.The development of HANDEY is part of the authors' long-term goal of achieving systems that can manipulate a variety of objects in different environments using a wide class of robots. HANDEY has been tested on numerous pick-and-place tasks, including parts ranging from wooden cubes to electric motors; it can be used to generate commands for different types of industrial robots, can coordinate two arms working in the same workspace, and has been tested with a module that locates the position of a specific part in a jumble of other parts.The first three chapters introduce the HANDEY system and task-level robot programming systems in general, address the problem of planning pick-and-place tasks, review areas of geometric modeling and kinematics required for subsequent chapters, and introduce the concept of configuration space, which plays a prominent role in HANDEY. The next four chapters describe how HANDEY operates.

  • Foundations of Cellular Neurophysiology

    Foundations of Cellular Neurophysiology

    Daniel Johnston and Samuel Miao-Sin Wu

    with simulations and illustrations by Richard Gray Problem solving is an indispensable part of learning a quantitative science such as neurophysiology. This text for graduate and advanced undergraduate students in neuroscience, physiology, biophysics, and computational neuroscience provides comprehensive, mathematically sophisticated descriptions of modern principles of cellular neurophysiology. It is the only neurophysiology text that gives detailed derivations of equations, worked examples, and homework problem sets (with complete answers). Developed from notes for the course that the authors have taught since 1983, Foundations of Cellular Neurophysiology covers cellular neurophysiology (also some material at the molecular and systems levels) from its physical and mathematical foundations in a way that is far more rigorous than other commonly used texts in this area.
