A good understanding of algorithms, and the knowledge of when to apply them, is crucial to producing software that not only works correctly, but also performs efficiently. This is the only book to impart all this essential information-from the basics of algorithms, data structures, and performance characteristics to the specific algorithms used in development and programming tasks.

Packed with detailed explanations and instructive examples, the book begins by offering you some fundamental data structures and then goes on to explain various sorting algorithms. You’ll then learn efficient practices for storing and searching by way of hashing, trees, sets, and maps. The authors also share tips on optimization techniques and ways to avoid common performance pitfalls. In the end, you’ll be prepared to build the algorithms and data structures most commonly encountered in day-to-day software development.

What you will learn from this book
* The basics of algorithms, such as iteration and recursion
* Elementary data structures such as lists, stacks, and queues
* Basic and advanced sorting algorithms including insertion sort, quicksort, and shell sort
* Advanced data structures such as binary trees, ternary trees, and heaps
* Algorithms for string searching, string matching, hashing, and computational geometry Continue Reading »

In October 2000, the US National Institute of Standards and Technology selected the block cipher Rijndael as the Advanced Encryption Standard (AES). AES is expected to gradually replace the present Data Encryption Standard (DES) as the most widely applied data encryption technology.|This book by the designers of the block cipher presents Rijndael from scratch. The underlying mathematics and the wide trail strategy as the basic design idea are explained in detail and the basics of differential and linear cryptanalysis are reworked. Subsequent chapters review all known attacks against the Rijndael structure and deal with implementation and optimization issues. Finally, other ciphers related to Rijndael are presented.|This volume is THE authoritative guide to the Rijndael algorithm and AES. Professionals, researchers, and students active or interested in data encryption will find it a valuable source of information and reference.

How the World Really Works and How to Make It Start Working Again! “For an engaging, insightful, and somewhat quirky take on how our economy works, The Econosphere is a must read. Craig Thomas does a masterful job of explaining basic economic fundamentals so that anyone can understand them and profit as a result.” –Mark Zandi, Chief Economist, Moody’s Economy.com “Classic Craig! Born with an ability to write informatively, Craig has delivered the layperson’s guide to everything economic! Clear, informative, and entertaining prose on the inner workings of the economy. A must read for anyone who wants to understand how the world works.” –Raymond G. Torto, PhD, Global Chief Economist, CB Richard Ellis “An engaging read. Craig’s view of what he calls ‘the Econosphere’ is really fascinating and is simply, yet eloquently, focused on what we can achieve as individuals and, at the same time, contribute to the betterment of mankind. This book encourages each of us to become stewards of the resources we use to sustain ourselves. It is a thoughtful, purposeful, and inspiring read.” –Steve Felix, Head of Real Estate Client Relations–North America, Aviva Investors, and author of Simplicate Your Life: Volume 1 “The Econosphere is a quick and enjoyable read with a powerful message. This fresh perspective on the workings of the economy is provided through surprising but logical comparisons to the environment and the green movement, combined with many witty anecdotes. I feel I have a new understanding of the economy’s nature. We should all be ‘green’ economists!” –Robert M. White, Jr., Founder and President, Real Capital Analytic. Continue Reading »
