10.2 How would you design the data structures for a very large social network like Facebook or Linkedln? Describe how you would design an algorithm to show the connection, or path, between two people (e.g., Me -> Bob -> Susan -> Jason -> You).…
摘要:Abstract—Complex social network analysis methods have been applied extensively in various domains including online social media, biological complex networks, etc. Complex social networks are facing the challenge of information overload. The demand…
2017 will see a host of informed predictions, lower costs, and even business-centric gains, courtesy of the global adoption of Big Data and associated technologies. 2017 is already upon us, and Big Data seems to be growing in leaps and bounds. Be it…
"I worked up a full implementation as well but I decided that it was too complicated to post in the blog. What I was really trying to get across was that immutable data structures were possible and not that hard; a full-on finger tree implementation…
原文链接:http://www.codeproject.com/Articles/9680/Persistent-Data-Structures Introduction When you hear the word persistence in programming, most often, you think of an application saving its data to some type of storage, such as a database, so that the…
refer:http://research.swtch.com/interfaces Go Data Structures: Interfaces Posted on Tuesday, December 1, 2009. Go's interfaces—static, checked at compile time, dynamic when asked for—are, for me, the most exciting part of Go from a language design…
What is a high-performance data structure? To answer that question, we're used to applying normal considerations like Big-Oh complexity, and memory overhead, locality, and traversal order. All of those apply to both sequential and concurrent software…
MapReduce: Simplified Data Processing on Large Clusters MapReduce:面向大型集群的简化数据处理 摘要 MapReduce既是一种编程模型,也是一种与之关联的.用于处理和产生大数据集的实现.用户要特化一个map程序去处理key/value对,并产生中间key/value对的集合,以及一个reduce程序去合并有着相同key的所有中间key/value对.本文指出,许多实际的任务都可以用这种模型来表示. 用这种函数式风格写出的程序自动就…
