    I generated a 1MB random file with this Pinetools random file generator but paq8pxd_v75 compress it 4 bytes smaller, so not a good tool to generate random files.

    Did you ever programmed a decompressor to see if one of your compressor outputs can be reversed back to the input and was binary identical?

    Yes, and not already one time. The version 1.0.0.1.7 of White hole Software can compress and extract files.

    Pinetools random file generator 1MB file option c compress 1 bytes smaller, decompress and file compare ok (same file paq8pxd_v75 compress 4 bytes smaller).

    1MB random.org file option c compress to 0 bytes, c1 compress to 1,050,441 bytes and c2 also to 0 bytes.

    If you can make it work at 10 different files from https://archive.random.org/binary you have something.

    Same file cmix v18 compress 532 bytes smaller.

    My compression can compress 1MB random file on 18 bytes. Predict information and write where it was.
    White hole algorithm compression random information
    We break information in block 4 bytes. We need to take information from the centre moves it to other places. When we move information x we write what where that was. We predict information and count it where it was that information. In centre information first bytes go long in bits of bytes second where it was from 1 to 2 bytes. We predict other information y and change it to information x. We predict 40 different information.

    And decompression and file compare?
    What happened at the random files you did not listed?

    We can compress and compress information.
    I can compress any file to <=300000 bytes.

    Amatuer. I can compress enwikk9 to 1 bit if i dont care about decompression.
    Once decompession is working then we can talk.

    You compression results are worthless without decompression

    Actually 1 bit is hard, since OS i/o is bytewise.
    In fact, 0 is easier, since we can assign it to any one specific file, which would have to be embedded in the decompressor.
    It would be even a perfectly valid compressor otherwise, like "filesize=0 ? output enwik8; otherwise decompress file data with cmix".

    I think that need to move information and write the
    prefix code.

    I like writing programs.

    c=0
    while c < -1:
    c=c+1
