Huffman Coding Algorithm create a priority queue Q consisting of each unique character. sort then in ascending order of their frequencies. for all the unique characters: create a newNode extract minimum value from Q and assign it to leftChild of newNode extract minimum value from Q and assign...
This article contains basic concept of Huffman coding with their algorithm, example of Huffman coding and time complexity of a Huffman coding is also prescribed in this article. Submitted by Abhishek Kataria, on June 23, 2018 Huffman coding

The special feature of adaptive Huffman coding algorithm is that, it has extremely accurate compression as well as it eliminates the repetition of dictionary based words in xml database. Using Adaptive Huffman algorithm, we derived probabilities which dynamically changed with the incoming data, through...

The windowed Huffman algorithm with an adaptive-size window performs as well as, or better than, that with an optimal fixed-size window. The new algorithm is well suited for online encoding and decoding of data with varying probability distributions.> 展开 ...
