### Algorithms & Data Structures in C++



[![Build Status][1]][2]



[1]: https://travis-ci.org/xtaci/algorithms.svg?branch=master

[2]: https://travis-ci.org/xtaci/algorithms



#### 目标 ( goal ) :



   1. 经典的算法实现      

      (classical algorithms implementations)      

   2. 服务器端       

      (based on linux/gcc)       

   3. 正确，易于使用和改造, 一个头文件一个算法，并附带一个demo.       

      (correct! and ease of use, one .header file per algorithm)        



#### 约定 ( Convention ):



   1.  一个算法用一个.h文件表示放到include下. ( one .header file per algorithm. )

   2.  算法演示的demo程序放到src下.  ( one demo per algorithm.  )

   3.  程序正确通过后，请发起Pull Requests，代码被验证后入库，并在README中发布新算法实现。

       (Please Use Fork+Pull Requests !!! Correctness is the most important!)

   4.  TAB = 4 space.  set ts=4 in vim

   5.  Graph的输出格式为 [Graphviz](http://www.graphviz.org/) Dot格式.

   	(the output format of the graph is in dot of graphviz.)

   	eg:

   	![demograph](demo_graph.png)
