ppmd_src
- 一个压缩算法, 名字叫PPMD,压缩率比较高, 同时, 可以自行修改并编译,请各位研究算法的同僚一同研究.-a compression algorithm, named PPMD, higher compression ratio, and can make its own decisions and build, please algorithm research colleagues to study together.
huffmanTree
- 在学习数据结构时,往往不知道那些结构与算法有何用,以及怎么用。这个小小程序充分显示了Huffman二叉树的应用。虽然其压缩效果比RAR相差甚远,但也能说明一二。 -the study data structure, they often do not know what the structure and algorithm, as well as how use. This little procedure fully demonstrated the application of th
Optimum-ratio-spanning-tree
- 本压缩程序为最优比例生成树算法的实现程序,代码完整。-The compression program is the realization of the optimal ratio of Spanning Tree Algorithm, code integrity.
TestCompress
- VC++演示LZARI压缩算法的使用效果,从事编程的朋友大概都听说过这个算法吧,据说压缩比还是可以的,虽然比不上WinRAR那么牛,但是在安全压缩方面也想当不错-VC++ demonstrates the use of effective compression algorithm LZARI engaged in programming the algorithm friends heard about it, said compression ratio is still possible,
LZW
- LZW压缩与解压 修改LZW压缩和解压的程序,完成下述要求: 1. 每完成xkbytes的文本压缩/解压,重新初始化码本(code table)。此过程可以看作是码本对文本内容的自适应调整过程,每编码部分文本后,码本重新初始化并根据后续文本内容生成,可以获得更好的压缩率。 2. 测试给出的文本文件,需要测试的x取值范围{10, 20, 30, 40, 50},并对比五种取值的压缩/解压效果(包括压缩率和压缩时间等)。程序参数需添加x,例如调用“Compress text 30”
