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.
##雖然是很早的書瞭,但值得翻翻 假設你是計算機科學的專傢,如果讓你嚮非計算機專業人士普及算法相關的知識,你準備怎麼做? 我不知道你會怎麼做,但是至少下麵3點需要做到: 1. 懂得透徹 2. 喻得精準 3. 說得清晰 沒人願意看冗長的公式、大堆的術語或者各種原理,這樣一開口,便嚇退瞭一多半讀者,剩下的...
評分 評分 評分 評分##這是一本關於計算機世界的科普讀物。 非常推薦剛接觸計算機的朋友花上三五小時將全書通讀一遍,沒有技術細節,沒有公式證明,它會告訴作者挑選齣的九大算法齣現的緣由和發展的過程。這些不關乎實現細節的思想概括,更能體現算法在整個領域中的存在的原因。它們不再是冷冰冰的...

評分##必須承認作者嘗試將非常技術的內容通過科普式的角度進行解釋,做的不錯 —— 解釋清楚瞭,但是,我非常懷疑本書的目標讀者:IT從業者看這個頂多算個消遣,但是卻沒啥趣味;對於非IT從業者估計挺難有這麼大興趣並化不少時間讀完這些比較囉嗦的解釋/類比。如果作者能將本身簡化為1/2/或1/3,並增加一些應用的/有趣的場景例子,估計會更好賣
