    Well yes it was one file, but it was stated as being good on text and enwik8 is a pretty standard test corpus for text compressors. I could have done more, but it somewhat vindicat…

    It doesn't compare itself against bsc, which feels a bit poor IMO given it's using Grebnov's libsais and LZP algorithm (he's the author of libbsc). On my own benchmarks, it's basic…

    As the author of the CRAM implementationn of rANS, I can say that these sort of articles aren't helpful. Clearly my work predates this by several years, so there is nothing here wh…

    Disclaimer - I am the author of the blog. There are no "comparisons with" CRAM in the MPEG-G preprint, only comparison between CRAM and DeeZ, taken from the DeeZ paper. Those compa…

    It's hard with huffman given you need to deal with N. Realistically you'll end up with 3 bases at 2 bits, 1 and 3 and the other 3 being a prefix for everything else (N, ambiguity c…

    To be "fair", their latest revision of the paper includes some figures from a 4 year out of date version of CRAM, which is an improvement on the 10 year old outdated format they us…
