    Smile Slowest Random General Lossless Compressor

    I programmed it, but it's really really slow. It takes an hour to compress 12 bytes to 7 bytes. And you can still compress that 7 bytes again. But the time it takes is it worth it? And How much would it worth? Because theoretically it can compress all types of files, and I believe with faster computer, and elegant code. It would take few seconds to compress.

    You can win 20k euro here: http://prize.hutter1.net/
    Have to decompress it rather than compress, though :)
    15284944*7/12 = 8916217
    50000*(15284944-8916217)/15284944 = 20833

    Don't you think 20k euro is too nano money for a true general random lossless compressor?

    First you need to have something you can actually sell.
    Like a US patent, or startup company based on your idea.
    An idea is not a product.
    With just an idea you can get a research grant or a job contract, but nothing luxurious.

    Then, there's also a cost/benefit analysis.
    The choice is not between storing the data with your algorithm, or not storing anything at all.
    But rather between getting more storage vs computing power required + extra latency.
    For a new algorithm with a speed similar to zlib there would be some applications,
    but we don't see cmix or nncp getting used to save storage space, because it wouldn't be profitable.
