具体描述
Every day, we use our computers to perform remarkable feats. A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and, we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

##Funny and easy to understand. How I wish he was my undergraduate professor
评分##Nice introduction to a world between my fingers.
评分##很浅，觉得两篇博客能讲清楚了
评分##适合没有任何基础的人阅读，有点啰嗦
评分##虽然是很早的书了，但值得翻翻
评分##Funny and easy to understand. How I wish he was my undergraduate professor
评分##能把复杂的东西通过这种通俗的语言和例子表述出来，真的很好，值得学习。看完了9个算法，没有看最后一章what's computable。特别喜欢前面2章，讲search engine和page rank。最后2章没有看那么仔细，跳着看的。
评分虽然文笔不怎么样，但确实用日常语言和例子解释了不少算法的基本理念。
