源码包包含两个文件，一个用于生成分类回归树，另一个用于画分类回归树的图例。使用时，只需调用cart.py。该代码能够实现未剪枝的分类回归树和剪枝的回归树。另外，该算法能同时以图的形式显示一颗分类回归树。

分形云（或灰尘）开始形成从一个用户定义的点P（A，B，X，Y），并通过大量的重复一些变换得到一些很酷的照片。因为事实上，我们可以顺着小径起点是离开（P0开始吧，p1-1st迭代，P2第二，的…PX即点图）图也被称为轨道（轨迹）的动态系统。得到一个粗鲁的估计是，B，X和Y是很好用的我你准备好clouds.xls。1 6张显示计算的序列这里给出的模式实例1 6。x()表显示图形的样子计算序列低接参数（有一些评论为什么）。提交575 K因为xls文件。

应用背景 Fifty Years of Shannon Theory： A brief chronicle is given of the historical development of the central problems in the theory of fundamental limits of data compression and reliable communication. 关键技术Shannon’s A mathematical theory of communication”published in July and October of 1948 is the Magna Carta of the information age. Shannon’s discoveryof the fundamental laws of data compression and transmission marks the birth of Information Theory. A unifying theory with profound intersections with Probability, Statistics, Computer Science, and other fields, Information Theory continues to set the stage for the development of communications, data storage and processing, and other information technologies.

一个LZW算法的实现，自带界面，可以压缩图片，文本文件等，还可以查看压缩率，压缩时间等

利用哈夫曼编码对文件进行压缩处理，并能从解压文件重新解压到原来的文件，可以显示压缩和解压时间，压缩文件以.cod后缀名保存，界面采用gtk编写，编译环境codeblocks 10.05.
