What is the best compression algorithm that allows random reads/writes in a file? I know that any adaptive compression algorithms would be out of the question. And I know huffman encoding would be out of the question. Does anyone have a better compression algorithm that would allow random reads/writes? I think you could use any compr...
I am told that Huffman coding is used as loseless data compression algorithm but also am told that real data compress software do not employ huffman coding,cause if the keys are not distributed decentralized enough,the compressed file could be even larger than the orignal file. This leave me wondering are there any real-world applicatio...
From my algorithms textbook: The annual county horse race is bringing in three thoroughbreds who have never competed against one another. Excited, you study their past 200 races and summarize these as probability distributions over four outcomes: first (“first place”), second, third, and other. Outcome Au...
So i must say that i love this site because its sooooo helpful and now i have another question! my Huffman tree which i had asked about earlier has another problem! here is the code: package huffman; import java.io.FileNotFoundException; import java.io.FileReader; import java.util.ArrayList; import java.util.PriorityQueue; import java...
I'm working on a library to work with Mobipocket-format ebook files, and I have LZ77-style PalmDoc decompression and compression working. However, PalmDoc compression is only one of the two currently-used types of text compression being used on ebooks in the wild, the other being Dictionary Huffman aka huffcdic. I've found a couple of i...
I read somewhere that organizing HTML attributes in a certain order can improve the rate of compression for the HTML document. (I think I read this from Google or Yahoo recommendation for faster sites). If I recall correctly, the recommendation was to put the most common attributes first (e.g. id, etc.) then put the rest in alphabetical ...
I'm not quite sure how to determine what the longest possible codeword is under Huffman encoding for a specific set of frequencies? Any ideas? ...
