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..

I have not made the change back to FGK, but for those who wonder, the algorithm is indeed an erroneous description of FGK algorithm (the error is mostly in description of the way nodes are numbered: "Numbers go down, and from right to left.") The paper mentioned by Vitter in the reference section makes this abundantly clear and there is no need to "search" the web. The reason I have not made the change is that this article needs to be written from ground up. 24.1.53.152 (talk) 07:16, 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]
