I'm not saying the "exact opposite" in my post to Arcilla. What I say there is that there have been preliminary ideas SIMILAR BUT NOT IDENTICAL to mine - and that there remains a gap between them and mine.

Arcilla, I was not aware of your remark when I wrote my book, "The Hidden Logic of Sudoku". Otherwise, I would have cited you. You had a great idea. Unfortunately, as I can see from the posts in this thread, nobody seems to have really understood it or pushed it further.

Based on more general ideas of symmetry, I came upon quite the same idea, formalised it. More generally, I introduced rn- and cn- spaces and an associated extended sudoku board to deal with them. I also extended the idea to chains, where it allows introducing completely new types of chains (hidden chains).
You can see more about this on my web pages (http://carva.oeg/denis.berthier) or on the Sudoku UK and Sudoku Programmers Forums.

As for your previous allusion to AICs as a proof that the rn, cn and bn- spaces "existed" before, that's a self-contradictory. AIC notation and the fierce attachment of AIC people to it is the ultimate proof that these people didn't understand that rc, rn, cn and bn spaces were exactly the same thing and should be dealt with the same way.

my argument isn't void because I didn't make my code public,

By any academic standard, if it's not public, you can make no claim about it.

Delusions of Grandure as always Denis, the main reasons most of us here do not interact with you over the years.

You do not even use A.I.C your self, refuse to do anything other then your own concepts don't even pretend to that I've alluded to something that didn't exists as concepts and bridge gaps.

Few used Aic in this time frame as it was developing, primary work was Niceloops as cellular atamata and that struggled with using cell based link sets outside of bilocals and bivavles, this did not require more then PM's and cells for operations.

Aic uses sector based Digit Xor logic gates found via the very initial constraints of a puzzles initiation
R, C, B Digit positions still active by the givens.

Acedmeics practices accept pré work unpublicated revealed later, by any parties with similar work and these are footnotes
Siting the first publicated work as it is.

My own work isn't why I brought it up stop kidding your self I make zero claim to be the first

stop using strawman tactics you are not the first publicated concepts those as sited by pat are older the only thing you did was collate and give names bAsed on your own work just like others predating you have.

I didn't "collate" anything. When I wrote [HLS1], I didn't even know the existence of the forums.
You're just spitting the same venom as 20 years ago. As you're unable to produce anything new, you need to diminish those that did.
That my last reply; I have no time to waste with you.

Lulz. Spitting venom never; that's been your own tastes.

"I didn't even know the existence of the forums" ignorance doesn't make my Statements Less true.

Just as much as people are unaware publicized work exists then and even today and yet still manage to find on their own the same/similar structures and logic operands doesn't make their own contributions less valid more of a reaffirmation their concepts are coherent if and when they find the existence of said objects.

And then I noticed it was done in the D language - which I never heard of til now! Looks like something I might want to learn. It is either that or Rust. I suspect D is not quite as hard to learn as RUST.

CSP-Rules is neither in D nor in Rust. It's in CLIPS, an AI language (not LISP, but a Lispian syntax). CLIPS is an inference engine. CLIPS itself is written in C and you can compile it just by typing "make" in the CLIPS/clips-core directory
In CLIPS, the rules are the code.

My BAD! I just keep leaping to wild conclusions. At least I am getting some good dialog that benefits me anyway!

4 spaces: have been around since befor 2005 on the defunct programmers forum with variations into how they store data
Mines been a 27 sector x 9 Digit : ( set) utilizing reference tables for visuall displays) broken down by the 9 sectors since 2006

Bad luck for you, there's a copy of the "defunct" programmer's forum: http://programmers.enjoysudoku.com/www.setbb.com/sudoku/indexe115.html?mforum=sudoku
You should be easily able to find references for your otherwise void claims.

Well I looked into that programmers archive DB and the problem is I don't know where to search to figure out what kind of luck is happening one way or the other? And I had heard dukuso had done some work in that area - something about 6-dimensions in this forum. The problem for me is with the crashing of forums and such leaves no record for me to look into. In an absolute sense, I really don't care for who invented what first - unless I get new insights from other sources. This is where those who go to the trouble of actually self-publishing their work in a dead tree format have an advantage! Books seem to last for hundreds and sometimes thousands of years. What is to say computer and web sites will even last the next few years! One big EMP pulse and perhaps it is ALL GONE! So, my introduction to 4-Grid was by Denis Bethier denis_berthier no matter where that came chronologically. DB's stuff is HARD but a least it is here! Self Publishing is NOT as BIG a deal as it once was! More of those who have something to say should consider it!
