    Okay, here is the PIMPLEv2 engine with High preset. This version requires about 224 MB of free RAM. However, this version not uses my newly invented LZP algorithm. I think, very soon I release a new Quad version with this amazing LZP compression. It's funny, but new LZP works much faster than current Quad, but compression is incomparable higher, note this is in cost of the decompression speed (now, decompression time = compression time). It's due to I think to myself Quad MUST have higher compression! By the way, new LZP in terms of compression time vs. compression ratio is my BEST creation!

    Thanks Ilia!

    Unfortunately I won't be able to test it until later as I am not at my home location.

    BTW: Can't wait for the Extreme "NEW MONSTER" preset version!

    I'm just hoping that there will soon be a version that compresses better than PPMonstr J rev.1 on Werner's SFC testset.

    And then we will see TC will see TC beating PPMonstr at the SFC test.

    Something is wrong!!!

    Matt Mahoneys test results for ENWIK8:
    tc 5.2 dev 2 (Feb. 7 2007) 32,417,139

    I have tested this myself and can verify that the correct compressed size for ENWIK8 should be 21,481,399 Bytes.

    Perhaps for mere error the mythical Matt Mahoney has reported the results of old version!
    tc 5.0 dev 2 (June 10 2006) 32,417,139 283,039,249
    tc 5.0 dev 4 (June 21 2006) 32,417,139 283,039,249
    tc 5.2 dev 2 (Feb. 7 2007) 32,417,139 283,039,249
    from "Large text compression benchmark"
    Here my results (tested on Pentium IV 3Ghz 1,8 GB MEM):
    ENWIK8 : 21.481.399 Bytes MEM: 230 MB
    ENWIK9: 184.939.711 Bytes MEM: 230 MB
    Great Ilia you are TOPGUN!

    Looks like Matt mistakenly tested an old version of TC (5.0dev2).

    I just sent him email!

    My mistake I should have noticed I got the same numbers as tc 5.0 dev 2. I will post the correct results shortly.

    Correct results have been posted now. TC now compresses better than 7-Zip 4.42 on this test!

    By the way, soon, and finally, I will add the Flexible Parsing to the TC! So, TC will have even higher compression. Also, probably Ill increase memory usage to 300+ or 400+ MB, so you must have 512 MB installed...

    I think you should also do a special high memory version (about 800 - 900MB) for benchmarking purposes only!

    PLEASE!

    Quoting MFC rules:
    ...Programs are allowed to use a maximum of 800 Mb memory.
    Okay, TC - is an experimental compressor and I think I can write a version with ~800 MB usage (to fit in MFC rules).

    So, TC is an experimental thing, and Quad is a practical compressor/compression engine! Cool!
