That was the qualitative observation that I based my formula for the relationship between the uniformity factor and the starting values on.

But the principles still stick a bit (: I agree, the uniformity factor should be tested for any given situation. What I was simply trying to validate was the relationship that I came up with. And I think it fits. Your spreadsheet is a great tool for testing this. I was going to write a program in C++ to do this, but I don't really see any point in doing so now. > As James Newton wrote: "In fact, I've been spending > a lot of time thinking about why this (PBK) project > bothers me so much and others have not....".

I don't know which. I support the sentiment, but I am neutral towards the practicality. If the majority like it, I'll do what I can to help out. If they don't, I'll probably keep commenting on various ideas that come up... I hope that you are keeping interest in this thread on randomness... I think it could see a multitude of uses if we can simply finish it up and formalize it. And your excel sheet is a good step in the right direction on that count. - --Brendan -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use iQA/AwUBPWFKMgVk8xtQuK+BEQKSGgCg2/eniSV/pRgxK1rsmgHAw5Y09s0AoLt+ upc5+w0fZeZ6p/9+G6Ymstsy =CBtK -----END PGP SIGNATURE----- -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
