具體描述
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.

##很好很明白，但過於簡單，隻適閤極其外行的朋友
評分##其實早就讀完瞭……
評分##通俗易懂，建議每個人都看看 等我的讀書劄記
評分##Clear and clever states for difficult concepts. May I do something similiarly?
評分##能把復雜的東西通過這種通俗的語言和例子錶述齣來，真的很好，值得學習。看完瞭9個算法，沒有看最後一章what's computable。特彆喜歡前麵2章，講search engine和page rank。最後2章沒有看那麼仔細，跳著看的。
評分##簡潔 易懂
評分##通俗易懂，建議每個人都看看 等我的讀書劄記
評分##偉大的思想都來自對生活細微處的思考。然而說實話，廢話太多（針對計算機係的來說)。
評分##非常淺顯
