Talk:Package-merge algorithm

[Untitled][edit]

I was in the process of adding several related topics. I kept this one short and then added the others. When I came back, there was this notice. I am going to add the information now. :) Sorry, Oravec 06:13, 7 November 2006 (UTC)[reply]

I will add the details within 48 hours. I wish to verify the information before adding it. Oravec 06:22, 7 November 2006 (UTC)[reply]

Although some references need to be added, the algorithm is now described. Faster algorithms for the length-limited Huffman coding problem exist, but they are too complicated for practical applications. Vegasprof 12:06, 7 November 2006 (UTC)[reply]

This page has come a long way. I've added a link from the Huffman coding page, particularly the Length-limited Huffman coding section. Hopefully the links will draw others to help put the final touches on this page. Oravec 15:00, 7 November 2006 (UTC)[reply]

Improvements since 1990[edit]

Someone needs to add a section on improvements and extensions to the algorithm that have been developed since 1990. For example, it is now known how to execute the package-merge algorithm using O(n) space. I would prefer that someone else, hopefully someone who is more of an expert in these latest developments, volunteer for this task. Vegasprof 03:11, 8 November 2006 (UTC)[reply]

Done; the appropriate sources are various Moffat/Turpin sources (so hopefully Managing Gigabytes should be good enough) and:

author = "L. L. Larmore and T. M. Przytycka",

title = "A Fast Algorithm for Optimal Height-Limited Alphabetic Binary-Trees",

journal = SICOMP,

volume = "23",

number = "6",

month = dec,

year = 1994,

pages = "1283-1312",

If anyone wants to add the refs appropriately and/or use math tags, they're welcome to do so. If not, hopefully I'll get around to it soon.... Calbaer 03:52, 8 November 2006 (UTC)[reply]

Ok Now, I Think[edit]

Shouldn't "importance" and "verify" be removed now? They were put up there some time ago, before the page was expanded to include so much detail and so many references. Vegasprof 10:09, 13 November 2006 (UTC)[reply]
