1 原理哈夫曼编码(Huffman Coding),又称霍夫曼编码,是一种编码方式,哈夫曼编码是可变字长编码(VLC)的一种。Huffman于1952年提出一种编码方法,该方法完全依据字符出现概率来构造异字头的平均长度最短的码字,有…

"bzip2" compresses files using the Burrows-Wheeler block-sorting text compression algorithm, and Huffman coding. Compression is generally considerably better than that achieved by more conventional LZ77/LZ78-based compressors, and approaches the performance of the PPM family of statistical compressors. It...
