TC 5.2dev2 is here!

**encode** · 5th February 2007, 16:37

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!

Thank you very much!

This new version outcompresses anything made by you I had my hands on!

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!

Quick SFC test...

Compression times still very quick!

Here the result in ENWIK8 21.481.399 bytes Fantastic!

**LovePimple** · 6th February 2007, 01:29

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

Currently Im waiting for maximumcompression.com update - too many programs stays untested!

**LovePimple** · 6th February 2007, 22:30

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

Something is wrong!!!

Matt Mahoneys test results for ENWIK8:

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

**Nania Francesco** · 9th February 2007, 12:11

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!

**Matt Mahoney** · 9th February 2007, 19:39

My mistake

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

**encode** · 9th February 2007, 20:03

Thank you!

**LovePimple** · 9th February 2007, 23:11

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...

Cant wait!

Finally TC *WILL* beat PPMonster on the SFC test!!!

**LovePimple** · 9th February 2007, 23:38

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

PLEASE!

**encode** · 9th February 2007, 23:46

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!

This is the compressor Im waiting for!
