- 哈夫曼树是相同个数的带权结点所构成的所有二叉树中带权路径长度WPL最小的二叉树,将其应用于计算机通信中数据编码技术可大大缩短电文代码的长度,且避免了电文代码二义性的产生。本文简要介绍了哈夫曼树的原理、构造方法及其在数据编码中的应用。-Huffman tree is the same as the number of nodes with the right posed by the Binary right path with the smallest length WPL binary tre

- 在一般的数据结构的书中,树的那章后面,著者一般都会介绍一下哈夫曼(HUFFMAN)树和哈夫曼编码。哈夫曼编码是哈夫曼树的一个应用。哈夫曼编码应用广泛,如JPEG中就应用了哈夫曼编码。 首先介绍什么是哈夫曼树。哈夫曼树又称最优二叉树,是一种带权路径长度最短的二叉树。所谓树的带权路径长度,就是树中所有的叶结点的权值乘上其到根结点的路径长度(若根结点为0层,叶结点到根结点的路径长度为叶结点的层数)。树的带权路径长度记为WPL=(W1*L1+W2*L2+W3*L3+...+Wn*Ln),N

huffman
- 哈夫曼(Huffman)树又称最优二叉树或最优搜索树,是一种带权路径长度最短的二叉树。在许多应用中,常常赋给树中结点一个有某种意义的实数,称此实数为该结点的权。从树根结点到该结点之间的路径长度与该结点上权的乘积称为结点的带权路径长度(WPL),树中所有叶子结点的带权路径长度之和称为该树的带权路径长度.(The Huffman (Huffman) tree, also known as the optimal two - fork tree or the optimal search tree,
