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.
用戶評價
##一本寫給沒有CS背景讀者的算法科普書，作者非常成功地做到瞭深入淺齣，運用很多形象的類比解釋清楚瞭密碼學/數字簽名/搜索引擎排名等最廣泛滲透到我們日常生活裏的算法。讀完最大的意外收獲是終於知道現在每天苦逼學習的抽象代數有什麼實際應用價值瞭。
評分##很好很明白，但過於簡單，隻適閤極其外行的朋友
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##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##簡潔 易懂
評分##適閤沒有任何基礎的人閱讀，有點囉嗦
評分##其實早就讀完瞭……
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##非常淺顯
