内容简介 ······
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.

评论 ······
非常浅显
伟大的思想都来自对生活细微处的思考。然而说实话，废话太多（针对计算机系的来说)。
Nice introduction to a world between my fingers.
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。
