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.
从最开始看这本书的时候就感觉到有些地方被翻译的莫名其妙,明明是很浅显的道理,却非得绕一个大圈子表达出来。越是看到内容较为复杂的部分,这种现象出现的就越是频繁,终于让我确定肯定是翻译出现了问题。从最短路径的Dijkstra算法一节中举例如下: 从本书第90页底部开始: ...
评分用了两天大致扫了一遍,剩了最后一章没有读,收获还是很多的。 当时读Master的时候没有好好学算法,混了一个学期,结果考试惨不忍睹。。。后来毕业的时候学校要求必须要过一门算法考试,才稍微认真的复习了一下,不过时间有限再加上资质平庸,CLRS上面讲的东西还是懵懵懂懂。 ...

贴近生活。讲到graph时,发现还是grokking 讲得更简洁易懂。接着往下看,越发觉得grokking 的妙 unlocked 的迷糊。空间直觉是思维本质,逻辑描述是不得已而为之。甭管作者名气多大, 把逻辑描述当作本质,就太。。。。后面一大半没兴趣了, 一堆乱糟糟的符号
