Approximating Huffman Codes in Parallel

In this paper we present some new results on the approximate parallel
construction of Huffman codes. Our algorithm achieves linear work
and logarithmic time, provided that the initial set of elements
is sorted. This is the first parallel algorithm for that problem
with the optimal time and ... more >>>

Parallel Construction of Minimum Redundancy Length-Limited Codes

This paper presents new results on parallel constructions of the
length-limited prefix-free codes with the minimum redundancy.
We describe an algorithm for the construction of length-limited codes
that works in $O(L)$ time with $n$ processors for $L$ the
maximal codeword length.
We also describe an algorithm for a construction ... more >>>
