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.

##通俗易懂，建議每個人都看看 等我的讀書劄記
評分雖然文筆不怎麼樣，但確實用日常語言和例子解釋瞭不少算法的基本理念。
評分##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##雖然是很早的書瞭，但值得翻翻
評分##沒有數學、沒有代碼，講的全部是“直覺”層麵的東西，神作！
評分##Nice introduction to a world between my fingers.
評分##適閤沒有任何基礎的人閱讀，有點囉嗦
評分##通俗易懂，建議每個人都看看 等我的讀書劄記
評分##很好很明白，但過於簡單，隻適閤極其外行的朋友
