It seems to me that you and Hutter are interested in a problem domain that consists of: 1. generating random turing machines 2. running them to produce output 3. feeding the output as input to another program P, which will then guess future characters based on previous ones 4. having P use these guesses to do compression May I suggest that instead you modify this problem domain by: (a) remove clause 1 -- it's not fundamentally interesting that output comes from a turing machine. Maybe instead make output come from a program (written by humans and interesting to humans) in a normal programming language that people would actually use to write code in (b) remove clause 4 -- compression is a bit of a red herring here, what's important is to predict future output based on past output. IMO if you made these changes, your problem domain would be a more useful one. While you're at it you may want to change the size of the "chunks" in each item of prediction, from characters to either strings or s-expressions. Though doing so doesn't fundamentally alter the problem. -- Philip Hunt, <[email protected]> Please avoid sending me Word or PowerPoint attachments.
