具體描述
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 card account 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 your smart phone? This book offers an engagingly written guide to the basics of computer algorithms. In Algorithms Unlocked, Thomas Cormen—coauthor of the leading college textbook on the subject—provides a general explanation, with limited mathematics, of how algorithms enable computers 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”); how to 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 financial relationships); how to solve problems that ask questions about strings of characters such as DNA structures; the basic principles behind cryptography; fundamentals of data compression; and even that there are some problems that no one has figured out how to solve on a computer in a reasonable amount of time.

##迴憶一些簡單的數據結構和算法，講的比較清楚。後麵有一些沒看懂
評分##貼近生活。講到graph時，發現還是grokking 講得更簡潔易懂。接著往下看，越發覺得grokking 的妙 unlocked 的迷糊。空間直覺是思維本質，邏輯描述是不得已而為之。甭管作者名氣多大， 把邏輯描述當作本質，就太。。。。後麵一大半沒興趣瞭， 一堆亂糟糟的符號
評分##算法入門。作者講得非常清楚，數學和僞代碼也都比較清楚。但後麵兩章還是有點難啊。希望CLRS讀完以後能更清楚理解這些算法。

評分##還行，不過還是慢點直接看clrs吧
