I have been doing research on entropy encoding for some time.. I found some interesting relationships between Arithmetic coding and other methods such as Huffman Coding. I made an article to explain them and am presenting here for review:

I have also attached a PDF version for convenience
**Arithmetic_Coding_Formula_based_approach.pdf** **612.85KB**
91 downloads.

Please let me know your ideas.
