    Sorry, I missed that sentence when (quick) reading.

    Test PC need to be behind a firewall what block Internet connection or without Internet connection while running "alien" (de)compression software.

    For example Krc could store and retrieve a dictionary in/from a remote cloud to save storage space and gain compression speed https://encode.su/threads/1935-krc-k...ll=1#post39550

    My preprocessor code crashed little over halfway Test 1 file Qualitative data (text only), I discovered some strange data there:

    ..."
    MARIE
    CECILIA
    MARIE
    CECILIA
    MARIE
    CECILIA (with a smile)
    MARIE
    ALBERT

    CECILIA
    "....

    Looks like missing sentences from original while names are listed:

    ..."
    MARIE

    Oh, that would be fine!

    CECILIA

    Did you hear that, Amadeus?

    AMADEUS (who has been standing a little way off)

    Certainly. It would be very nice.... You can wait for us in the Tirol.

    CECILIA

    Could you come and see me to-morrow afternoon, Marie? Then we might settle the matter.

    MARIE

    Yes, indeed. I am always glad when you can spare me a little of your time.—Until to-morrow, then!

    ALBERT

    Good-by. (He and Marie go out)

    AMADEUS (is walking to and fro)

    CECILIA (who is sitting on the couch, follows him with her eyes)

    AMADEUS (after a turn to the window and back, speaking in a peculiarly dry tone) Well, how did it go? Have you got the finale into shape at last?

    CECILIA

    Oh, in a manner.

    AMADEUS

    The day before yesterday it had not yet been brought up to the proper level. I find, for one thing, that they don't let you assert yourself sufficiently. Your voice should be floating above the rest, instead of being submerged in the crowd.

    CECILIA

    Won't you come to the rehearsal to-morrow—just once more—if you can spare the time?

    AMADEUS

    Would it please you...?

    CECILIA

    I always feel more certain of myself when you are within reach. You know that, don't you?

    AMADEUS

    Yes—I'll come. I'll call off my appointments with Neumann and the Countess.

    CECILIA

    If it isn't too great a sacrifice....

    AMADEUS (with assumed brusqueness)

    Oh, I can make her come in the afternoon.

    CECILIA

    But then there will be no time left for your own work. No, better let it be.

    AMADEUS

    What had we better let be?

    CECILIA

    Don't come to the rehearsal to-morrow.

    Might be a bug in my filter script. But I don't think its a good reason to change anything.
    In fact, isn't it a good dataset if it lets you detect preprocessors bugs? :)

    I knew the situation what caused the crash could happen in theory, but I didn't expect it with this text file, so indeed it's a good dataset for lazy programmers

    I might as well join this competition. We have up to Nov. 20, 2020, hmm?

    First, since my dual-core computer crashed, i have to buy a new computer. And i have to learn how to install g++ again oh my! (but i still got bcc32). After almost a decade, i might be coding again. Brave.

    Tried entering lzuf2 as a test submission, but gmail failed to send. Now email is "queued".

    Will sponsor Huawei own the submitted compressors? If not, will it buy the winning compressor?

    Reverse engineering is enough.
    Therefore, I don't like to share compressors between competitors.

    After a first quick glance, testset 3 looks fine. Looking for compressed leftovers, only found this one so far (very small ZIP part, 210 bytes decompressed).

    This is the most interesting testset for me, because this kind of data dominates things like Android APK files and is a mix of structured pointer lists, program code and string sections (e.g. method names), so some preprocessing (parsing and reordering stuff, detecting structured data) should be the way to go and would help compressing data like this.

    Left side is from the original file, right side is the output of "Precomp -cn"

    TS40.txt is not an ASCII, even not an Latin-1 file. It contains characters left over from UTF-8 (with decimal codes 128, 145, 147, 225, 226). For example see next line after line

    "Thank Heaven! . . . . Good-night."

    Or see next word after

    The description says "texts from Project Gutenberg in UTF-8 characters, so it’s essentially ASCII", not that its ASCII.

    > It contains characters left over from UTF-8

    That's intentional in this case. No need to make it too simple.
