Analytic combinatorics aims to enable precise quantitative predictions of the properties of large combinatorial structures. The theory has emerged over recent decades as essential both for the analysis of algorithms and for the study of scientific models in many disciplines, including probability theory, statistical physics, computational biology, and information theory. With a careful combination of symbolic enumeration methods and complex analysis, drawing heavily on generating functions, results of sweeping generality emerge that can be applied in particular to fundamental structures such as permutations, sequences, strings, walks, paths, trees, graphs and maps. This account is the definitive treatment of the topic. The authors give full coverage of the underlying mathematics and a thorough treatment of both classical and modern applications of the theory. The text is complemented with exercises, examples, appendices and notes to aid understanding. The book can be used for an advanced undergraduate or a graduate course, or for self-study.

There's nothing that hard-core Unix and Linux users are more fanatical about than their text editor. Editors are the subject of adoration and worship, or of scorn and ridicule, depending upon whether the topic of discussion is your editor or someone else's. vi has been the standard editor for close to 30 years. Popular on Unix and Linux, it has a growing following on Windows systems, too. Most experienced system administrators cite vi as their tool of choice. And since 1986, this book has been the guide for vi. However, Unix systems are not what they were 30 years ago, and neither is this book. While retaining all the valuable features of previous editions, the 7th edition of Learning the vi and vim Editors has been expanded to include detailed information on vim, the leading vi clone. vim is the default version of vi on most Linux systems and on Mac OS X, and is available for many other operating systems too. With this guide, you learn text editing basics and advanced tools for both editors, such as multi-window editing, how to write both interactive macros and scripts to extend the editor, and power tools for programmers -- all in the easy-to-follow style that has made this book a classic. Learning the vi and vim Editors includes: A complete introduction to text editing with vi: * How to move around vi in a hurry * Beyond the basics, such as using buffers *vi's global search and replacement * Advanced editing, including customizing vi and executing Unix commands How to make full use of vim: * Extended text objects and more powerful regular expressions * Multi-window editing and powerful vim scripts * How to make full use of the GUI version of vim, called gvim *vim's enhancements for programmers, such as syntax highlighting, folding and extended tags Coverage of three other popular vi clones -- nvi, elvis, and vile -- is also included. You'll find several valuable appendixes, including an alphabetical quick reference to both vi and ex mode commands for regular vi and for vim, plus an updated appendix on vi and the Internet. Learning either vi or vim is required knowledge if you use Linux or Unix, and in either case, reading this book is essential. After reading this book, the choice of editor will be obvious for you too.

Every day you answer questions-dozens, even hundreds of them. How do you find the answers to questions? How can you be sure your answers are correct? Scientists use questions to learn about things. Scientists have developed a way of helping make sure they answer questions correctly. It is called the scientific method. The scientific method can help you find answers to many of the questions you are curious about. What kind of food does your dog like best? Is your sister more likely to help you with your homework if you say please? Can throwing a dead snake over a tree branch make it rain? The scientific method can help you answer these questions and many others. Stephen Kramer's invitation to think like a scientist, illustrated by Felicia Bond's humorous and appealing pictures, will receive enthusiastic response from young readers, scientist and nonscientist alike.

Java is a new object-oriented programming language that was developed by Sun Microsystems for programming the Internet and intelligent appliances. In a very short time it has become one of the most widely used programming languages for education as well as commercial applications.Design patterns, which have moved object-oriented programming to a new level, provide programmers with a language to communicate with others about their designs. As a result, programs become more readable, more reusable, and more easily extensible.In this book, Matthias Felleisen and Daniel Friedman use a small subset of Java to introduce pattern-directed program design. With their usual clarity and flair, they gently guide readers through the fundamentals of object-oriented programming and pattern-based design. Readers new to programming, as well as those with some background, will enjoy their learning experience as they work their way through Felleisen and Friedman's dialogue.

How to Break Software is a departure from conventional testing in which testers prepare a written test plan and then use it as a script when testing the software. The testing techniques in this book are as flexible as conventional testing is rigid. And flexibility is needed in software projects in which requirements can change, bugs can become features and schedule pressures often force plans to be reassessed. Software testing is not such an exact science that one can determine what to test in advance and then execute the plan and be done with it. Instead of a plan, intelligence, insight, experience and a "nose for where the bugs are hiding" should guide testers. This book helps testers develop this insight. The techniques presented in this book not only allow testers to go off-script, they encourage them to do so. Don't blindly follow a document that may be out of date and that was written before the product was even testable. Instead, use your head! Open your eyes! Think a little, test a little and then think a little more. This book does teach planning, but in an "on- the-fly while you are testing" way. It also encourages automation with many repetitive and complex tasks that require good tools (one such tool is shipped with this book on the companion CD). However, tools are never used as a replacement for intelligence. Testers do the thinking and use tools to collect data and help them explore applications more efficiently and effectively.

The book is Volume 4A, because Volume 4 has itself become a multivolume undertaking. Combinatorial searching is a rich and important topic, and Knuth has too much to say about it that is new, interesting, and useful to fit into a single volume, or two, or maybe even three. This book alone includes approximately 1500 exercises, with answers for self-study, plus hundreds of useful facts that cannot be found in any other publication. Volume 4A surely belongs beside the first three volumes of this classic work in every serious programmer’s library.

The first edition of C Programming: A Modern Approach was popular with students and faculty alike because of its clarity and comprehensiveness as well as its trademark Q&A sections. Professor King's spiral approach made it accessible to a broad range of readers, from beginners to more advanced students.
