Have you ever wondered how your GPS can find the fastest way to your destination,selecting one route from seemingly countless possibilities in mere seconds? How your credit cardaccount number is protected when you make a purchase over the Internet? The answer is algorithms.And how do these mathematical formulations translate themselves into your GPS, your laptop, or yoursmart phone? This book offers an engagingly written guide to the basics of computer algorithms. InAlgorithms Unlocked, Thomas Cormen -- coauthor of the leading college textbook onthe subject -- provides a general explanation, with limited mathematics, of how algorithms enablecomputers to solve problems. Readers will learn what computer algorithms are, how to describe them,and how to evaluate them. They will discover simple ways to search for information in a computer;methods for rearranging information in a computer into a prescribed order ("sorting"); howto solve basic problems that can be modeled in a computer with a mathematical structure called a"graph" (useful for modeling road networks, dependencies among tasks, and financialrelationships); how to solve problems that ask questions about strings of characters such as DNAstructures; the basic principles behind cryptography; fundamentals of data compression; and eventhat there are some problems that no one has figured out how to solve on a computer in a reasonableamount of time.
