Abstract
A method for deriving optimal upper bounds on the redundancy of binary Huffman codes in terms of the probability p 1 of the most likely source letter is presented. This method will be used to compute bounds for all p 1⩾1/127, which were previously known only for a few special cases. Furthermore, the known optimal lower bound for binary Huffman codes is generalized to arbitrary code alphabets and some upper bounds for D -ary Huffman codes, 2⩽D <∞, are given, which are the tightest possible for all p 1⩾1/2
