Generalization of known methods of string coding

The first part of this paper is about Huffman coding. Its key feature is a binary tree construction. This tree defines recursive partition of alphabet set to construct prefix codes. Generalization of binary tree to q-ary tree is well known. This paper gives Huffman coding generalization for any trees. The second part of this paper defines another approach to understanding Lembel-Ziv family of algorithms. The suggestion is that these algorithms encode a mapping associated with a string, not a string itself. The string is a fixed point of encoded mapping in this case.

Key Words
