Are you good with maths and C programming and enjoy new interesting algorithms? I need you to write code in C (not C++) an existing algorithm which estimates how much a buffer (eg. a file) can be compressed. Note that it does not actually compress a buffer - it is not a compression algorithm. Instead it makes an estimate - it determines approximately how much a buffer can be compressed, and it does this very fast (if it wasn't fast there would be no point as we would just compress it to find out the size). The ALGORITHM is described in full at: [login to view URL] Please read through the PDF to ensure you understand it before making a bid offer, and indicate in your bid that you understand it. The PDF describes two estimation algorithms (for RLE and LZ77), but I only need you to do the LZ77 one, not the RLE one. (And again just to be clear, this isn't the actual LZ77 algorithm, it's an algorithm which estimates how much an LZ77-based compressor could compress a buffer - much faster than actual compression). The resulting C program (a simple console app is all that's needed, nothing fancy) should simply accept one parameter (a filename), and then printf the compressibility of that file's data, eg "Compression estimation for this file: 36.789%" I am not in any particular rush for this, so if you need to take a few weeks that's fine - I need _quality_ code, not quick code! :) I look forward to working with you

Hello. I have briefly checked PDF, and it looks like there is Lower estimation and Higher estimation. Is not it? Therefore I think it should print both lower estimation and higher estimation...

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on server side, using c++ under Linux environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

i can code for you in for finding compression percent LZ77. I ll have to have a quick study on LZ77 to start the project. But i can do the project and has done similar complicated project in various languages. I develop code myself and i am not a mediator. Feel free to contact me via chat so that we can discuss about it. Thanks.
