Greetings Compressor Heads, Over the last month or so I have been working on various data compression projects. These have been: * LZRW1-A * LZRW2 * LZRW3 * LZRW3-A * Interface standard * LZRW4 * LZRW5 Unfortunately, I now have to turn to other things, and progress of the unfinished projects (Interface standard, LZRW4, and LZRW5) is now likely to be intermittant, erratic, and perhaps even permanently postponed (the standard stands a good chance though). Rather than waiting until I can post production versions of LZRW4 and LZRW5 (as I have done with the other algorithms) I have decided to write up and post brief descriptions of the ideas behind them, along with the experimental half-baked code that I have already written. This will create a prior art context that will prevent the ideas from being rediscovered and patented by others. Both LZRW4 and LZRW5 introduce ideas that, to my knowledge, are new. I hope you find the ideas interesting. I will read with interest any postings or email on these ideas, but may not always have the time to prepare detailed replies. Enjoy, Ross Williams ross@spam.ua.oz.au
