The Art of Lossless Data Compression vol. 24b

Here are the results of tests performed in August 2002 to compare lossless compression of "binary" files by all known good enough programs developed for such purpose, including RK, DC, YBS, Bzip2, RAR, ACE and 7-zip. See Archive Comparison Test by J.Gilchrist for more details: http://compression.ca If anybody wants to start or continue such tests, or can suggest some other sets of files, or other compression programs, (not sources or algorithm descriptions, executable programs only) or knows we have missed something important, (some new fantastic technology, an algorithm or even a program capable of lossless compression of up to 1000:1 etc.) please let us know immediately: artest@inbox.ru Thank you!

compression time, extraction time, and time it would take to transfer the compressed file over a 28,800bps network: (compressed_size)/3600 Average Users' score is calculated by adding (compress_time/10)+ extract_time + time it would take to transfer the compressed file over a 28,800bps network. Compression time is divided by 10 here, because more than 90% of people would never compress anything during their life (with compression programs), but they use compressed data almost _every_ time they use computers and/or Internet. That's why compression time is not so actual for them.

FULL version contains all *.BAT and *.DAT files you'll need to build 10 directories with 5960 files (artest24.zip\COOK_SET\*.*) and to repeat all our tests (BINS.BAT, BINARIES.DAT). Some old or less efficient programs will not be included next time: 777, UFA, BIX, ACB, BA, PPMy. WARNINGS: ~~~~~~~~~ BA 1.00beta5 can't losslessly decompress many files: CUN5IF~1.bin, CUN6IF~1 etc It types nothing like "CRC fails". DC 0.99.158b fails to decompress HLPCOPY..bin, but only if you compress with "-mb5" switch and [] filename like "any.dc5". Says nothing like "CRC fails". Problems in all other compressors were not found. The LATEST RELEASE, and all previous versions of these tests can be found at http://geocities.com/SiliconValley/Bay/1995/ and http://artest1.tripod.com/ Send your suggestions, comments to artest@inbox.ru With best kind regards, A.Ratushnyak Back to main ARTest page
