Hi, everyone.

I put up this article because, IMHO, an adaptive technique deserves a walktrough. But I'm in doubt, maybe just erase it and give a bunch of links to good sites, even merge to Huffman.

And that thing with numbers seems to be just a heap structure trick, maybe even propritary. Highest number == Topmost right.

FGK -> Vitter

The algorithme described is the Vitter alg., not the FGK alg..

See also http://www.cs.duke.edu/csed/curious/compression/adaptivehuff.html

I have not made the change back to FGK, but for those who wonder, the algorithm is indeed a bad description of FGK algorithm. The paper mentioned by Vitter in the reference section makes this abundantly clear and there is no need to "search" the web to verify this. —Preceding unsigned comment added by 24.1.53.152 (talk) 07:13, 9 December 2009 (UTC)[reply]

Swap

I don't understand one thing: should the nodes be swapped together with its subtree? I guess it is so so that the weights correspond and so that the tree can change its shape. Yet, I may have missed something. --Honnza 08:25, 14 July 2006 (UTC)[reply]
