A Dynamic Programming Approach to Length-Limited Huffman Coding: Space Reduction With the Monge Property
Summary form only given. We present a parallel algorithm for the construction of minimum redundancy length-restricted codes that is based on the package-merge algorithm of Larmore and Hirschberg (1990). Our algorithm constructs a length-restricted code in O(L) time with n processors on a CREW PRAM. Thus our algorithm has the same time-processor product as the sequential algorithm of (1990). We also consider the problem of constructing the almost-optimal length-restricted codes.
