如果数学不好，是否可以成为一名程序员呢？答案是肯定的。 本书最适合：数学糟糕但又想学习编程的你。 没有晦涩的公式，只有好玩的数学题。 帮你掌握编程所需的“数学思维”。 日文版已重印14次！ 编程的基础是计算机科学，而计算机科学的基础是数学。因此，学习数学有助于巩固编程的基础，写出更健壮的程序。 本书面向程序员介绍了编程中常用的数学知识，借以培养初级程序员的数学思维。读者无需精通编程，也无需精通数学，只需具备四则运算和乘方等基础知识，就可以阅读本书。 书中讲 解了二进制计数法、逻辑、余数、排列组合、递归、指数爆炸、不可解问题等许多与编程密切相关的数学方法，分析了哥尼斯堡七桥问题、少年高斯求和方法、汉诺塔、斐波那契数列等经典问题和算法。引导读者深入理解编程中的数学方法和思路。 本书还对程序员和计算机的分工进行了有益的探讨。读完此书，你会对以程序为媒介的人机合作有更深刻的理解。

A fascinating exploration of how insights from computer algorithms can be applied to our everyday lives, helping to solve common decision-making problems and illuminate the workings of the human mind All our lives are constrained by limited space and time, limits that give rise to a particular set of problems. What should we do, or leave undone, in a day or a lifetime? How much messiness should we accept? What balance of new activities and familiar favorites is the most fulfilling? These may seem like uniquely human quandaries, but they are not: computers, too, face the same constraints, so computer scientists have been grappling with their version of such issues for decades. And the solutions they've found have much to teach us. In a dazzlingly interdisciplinary work, acclaimed author Brian Christian and cognitive scientist Tom Griffiths show how the algorithms used by computers can also untangle very human questions. They explain how to have better hunches and when to leave things to chance, how to deal with overwhelming choices and how best to connect with others. From finding a spouse to finding a parking spot, from organizing one's inbox to understanding the workings of memory, Algorithms to Live By transforms the wisdom of computer science into strategies for human living.

群体智能是近年来发展迅速的人工智能学科领域.通过研究分散,自组织的动物群体和人类社会的智能行为, 学者们提出了许多迥异于传统思路的智能算法, 很好地解决了不少原来非常棘手的复杂工程问题.与蚁群算法齐名的粒子群优化(particle swarm optimization, 简称PSO)算法就是其中最受瞩目,应用最为广泛的成果之一. 本书由粒子群优化算法之父撰写,是该领域毋庸置疑的经典著作.作者提出,人类智能来源于社会环境中个体之间的交互,这种智能模型可以有效的应用到人工智能系统中去. 书中首先从社会心理学, 认知科学和演化计算等多个角度阐述了这种新方法的基础,然后详细说明了应用这些理论和模型所得出的新的计算智能方法--粒子群优化,进而深入探讨了将粒子群优化应用于广泛的工程问题.

Gerd Gigerenzer's influential work examines the rationality of individuals not from the perspective of logic or probability, but from the point of view of adaptation to the real world of human behavior and interaction with the environment. Seen from this perspective, human behavior is more rational than it might otherwise appear. This work is extremely influential and has spawned an entire research program. This volume (which follows on a previous collection, Adaptive Thinking, also published by OUP) collects his most recent articles, looking at how people use "fast and frugal heuristics" to calculate probability and risk and make decisions. It includes a newly writen, substantial introduction, and the articles have been revised and updated where appropriate. This volume should appeal, like the earlier volumes, to a broad mixture of cognitive psychologists, philosophers, economists, and others who study decision making.

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.

搜索引擎作为互联网发展中至关重要的一种应用，已经成为互联网各个领域的制高点，其重要性不言而喻。搜索引擎领域也是互联网应用中不多见的以核心技术作为其命脉的领域，搜索引擎各个子系统是如何设计的？这成为广大技术人员和搜索引擎优化人员密切关注的内容。 本书的最大特点是内容新颖全面而又通俗易懂。对于实际搜索引擎所涉及的各种核心技术都有全面细致的介绍，除了作为搜索系统核心的网络爬虫、索引系统、排序系统、链接分析及用户分析外，还包括网页反作弊、缓存管理、网页去重技术等实际搜索引擎必须关注的技术，同时用相当大的篇幅讲解了云计算与云存储的核心技术原理。另外，本书也密切关注搜索引擎发展的前沿技术：Google的咖啡因系统及Megastore等云计算新技术、百度的暗网抓取技术阿拉丁计划、内容农场作弊、机器学习排序等。诸多新技术在相关章节都有详细讲解，同时对于社会化搜索、实时搜索及情境搜索等搜索引擎的未来发展方向做了技术展望。为了增进读者的理解，全书大量引入形象的图片来讲解算法原理，相信读者会发现原来搜索引擎的核心技术理解起来比原先想象的要简单得多。
