Your solver is impressive.

I downloaded version labeled "Version: V1.0.0 dated June 24th 2011", and after some reverse engineering found the basic command line syntax. It runs about 30-200 times faster than SE, processing a batch of 300K non-average puzzles in 1h 23'.

Some basic documentation is welcome. It is up to you in choosing where or whether to open a discussion.

I'll answer to your post this morning in that thread

http://forum.enjoysudoku.com/cloning-sudoku-explainer-thru-tagging-t30132.html#p211792

To make it short, what you downloaded is skfr, a "quasi clone" of serate the rating part of Sudoku explainer;

My solver works on completely different rules.

I think we can use the pointed thread to discuss on both.

the release V 1.0.0 is somehow outdated. I am just finishing preliminary tests to produce a V 1.1.0 with the same limitation (level 2 in serate chains) but including many adjustments, mainly those required after having made comparative tests between V.1.0.0 an serate.

the release V.2.0.0 should include the level 2.

level 2 in serate includes some ratings in the range 9.8/11, but not all of them

Hi champagne,

I saw that your program could be downloaded.
Embarrassing enough, I haven't managed to find where.
I would really like to try it!

Again, to be quite clear, this is not my solver, but skfr, the "quasi clone" of Suduku explainer rating subroutine "serate" in construction as explained here.

http://forum.enjoysudoku.com/cloning-sudoku-explainer-thru-tagging-t30132.html

The code is located in google database and work as a "team project"
It can be accessed with that link

http://code.google.com/p/skfr-sudoku-fast-rating/

Getting a copy of my solver is not a problem but would require preliminary private discussions.

You need to have three posts to be able to send private messages.

41-given non-minimal 10.4

Postby dobrichev » Mon Sep 12, 2011 7:58 pm

Here is one non-minimal puzzle with 999911111 digit distribution.

Code: Select all
.6..12.34.13.74.2.2.43..1....2.314..13.4..8.24..2...13.21.4.3...4..932.13..12..45 10.4/10.4/10.0


Here are its 23-clue minimals - 11111-part fixed, non-givens fixed, 9999-part minimized.
(First 5 of them have reduced rating).
Edit: as mentioned by Mauricio and champagne, the first 5 are not minimals from the same seed, sorry.

Those 5 puzzles are not minimals of the original (8@r9c3 not in original puzzle), otherwise, nice findings.

These 5 can not be a minimal form of the seed
They have an extra digit '8'

But that 10.4 with so many digits is amazing

Hi Mauritio and champagne,

Thank you for the correction.

Is this puzzle still a candidate for best non-diamond (silicon)?
