I can't see any a priori reason why this would be impossible. What happens very often is the BRT-expand of a B7B+ minimal puzzle having B6B- minimals.
But who knows if you consider only B7B+ puzzles; then, very strange things happen, such as the resolution paths having a gap of eliminations between B7B and their BxB.

Just seeing your second post.

hendrik_monard wrote:Some second thoughts about different BxB ratings for a given solution. There are now a large number of minimals of non minimal B7B+ puzzles available. Has someone tested if among those minimals there are some with different BxB ratings? I imagine that this could be the case for 'higher' expansions.

If you don't restrict the minimals to those in B7B+, you'll easily find counter-examples, even puzzles in T&E(1).
I've done a quick statistical study of the minimals of BRT and BRT+1 expands of B7B+ minimals. See details in [HCCS2], sections 6.2.3 and 6.2.4. For the 3 known B14B, we can already say that all the minimals of their BRTR+1 expands are in B14B or in B6B- or T&E(1). I'll see if I can extract relevant information for other individual puzzles.

Probably like many questions in Sudoku, if true of all the known examples: impossible to prove.

hendrik_monard wrote:I can imagine that some 'higher' expansion has a lower BxB rating. In that case you would have different BxB rating for the same solution. Or must the search be limited to minimal puzzles or min_expands?

Between the characteristics of minimals of BRT and BRT+1 expansions, I didn't see much difference.

After reviewing my calculations for coloin's BXB-Mastermins collection of 3362 B7B+ minimal puzzles (Sept. 2024), it appears I had computed the following - which doesn't appear in [HCCS2] (July 2024).
I studied the B10B and B9B sub-collections, their BRT and BRT+1 expansions and the minimals of the latter two.

1) B10B: 1,184 puzzles
- 581 non-isomorphic BRT-expands
- giving rise to 1,184 minimal puzzles (which can only be the same as at the start): the B10B sub-collection is closed under BRT-expansion and minimisation

-28,853 non-isomorphic BRT+1-expands
- giving rise to 105,521 minimals
- only 63,693 of which are at T&E-depth 2
- with the following BxB distribution:
Code: Select all
(X-distribution-p-to-q "Coloin-2024-09-03-B7B/B10B/U-BRT+1-TE2-BxB.txt" 63693 0 10)
0: 0
1: 319
2: 33833
3: 25543
4: 2374
5: 254
6: 154
7: 0
8: 0
9: 32
10: 1184

No new B10B appears, but 32 B9B have appeared.

As BRT+1 expansion doesn't produce new solution grids, the conjecture is disproved!


2) B9B: 1,163 puzzles
- 419 non-isomorphic BRT-expands
- giving rise to 1,163 minimal puzzles (which can only be the same as at the start): the B9B sub-collection is closed under BRT-expansion and minimisation
I haven't studied the BRT+1 expansions

3) B8B: 244 puzzles
- 86 non-isomorphic BRT-expands
- giving rise to 244 minimal puzzles (which can only be the same as at the start): the B8B sub-collection is closed under BRT-expansion and minimisation

ahhh I see now that there are some puzzles in your recent list which were already known. I guess its difficult to purge the expanded forms, but easier to purge the minimals.
Expanding the puzzles to maximal BXB in my hands isnt completely reliable..perhaps rarely missing a few clues at the top end.
This happened here, the duplicate puzzles are all in the BxB 10 with 10 twins ... 18 twins found with the extra clue.
Code: Select all
...4.67..4..18.2.6....27....96.......48261...5.1...6.....81.4.2..46.2..1..2.7486. #10#12#   720 FNBP C33/M2.74.88
...4.67..4..18.2.6....27....96.......48261...5.1...6.....81.4.2..46.2.71..2.7486. #10#18#   734 FNBP C34/M2.91.72

I guess what we need is a complete file of minimal puzzles and a complete file of max expands...[ as denis suggests !] so will combine them

Here is a reliable procedure (k fixed):
Let S be a set of minimal puzzles with BxB = k
1) expand all of the puzzles in S by Singles : you can be sure they all have BxB = k
2) compute all the 1-expands of all the previous puzzles, they can only have BxB ≤ k; keep only those with BxB = k
3) if the above remaining set is not empty, goto 1

Indeed, we need 3 sets: minimals, min-expands, max-expands

I've now checked the full coloin's Mastermind and Masterminds4 collections of minimal B7B+ puzzles according to the following process:
- split each collection into sub collections of constant BxB
- for each sub-collection:
--- compute the BRT-epxands (Singles-expands)
--- eliminate redundancies (using gsf's software)
--- generate all the minimal puzzles (with no redundancies, using gsf's software)
--- question : do we get puzzles with a different BxB?
--- answer: NO ! Indeed, we get exactly the same number of puzzles as at the start (which can therefore only be isomorphic forms of the original ones).
Conclusion : for these collections, digging for minimals in the BRT-vicinity of a minimal puzzle doesn't produce puzzles with a different BxB classification.
(As mentioned in a previous post, replacing BRT-vicinity by a larger BRT+1-expansion wouldn't preserve this result.)
The result is undoubtedly related to the presence of a tridagon, but why it is true is still eluding me.

.

In the mean time, a quick procedure for checking if a new solution has been found is available:
1) transform the puzzle to the solution minlex isomorph (if it is not already done)
2) solve the puzzle
3) check if the solution is not in the B7B+ solutions database, currently available on my google drive at the link provided on December 19th.
That's how I do it.
I tried to add the 5 recently found new solutions to this database, but it seems to be impossible. So it looks like I'll have to change the link after each extension of the database, unless someone knows if and how an existing document on the google drive can be modified.

Hi coloin

I've put the 4 files in gsf-solution-minlex form, added them (=> 5339 puzzles), eliminated redundancies (=> 4190 different puzzles), computed unique minimals (some of them weren't minimals).
I finally get 6259 minimals, corresponding to 781 different solution grids.
Here's a link to the two files:
https://drive.google.com/file/d/1RQmKsyLC2e3gpRgOdWJCP7CPJS73-9Z4/view?usp=sharing
The distribution of ratings (from 7 to 14) is:
Code: Select all
7: 998
8: 534
9: 2239
10: 2423
11: 24
12: 0
13: 38
14: 3
% = (15.95 8.53 35.77 38.71 0.38 0.0 0.61 0.048)



The most surprising point is, most of those solutions grids (653/781 Edit: 776/781) are not in the 67359 ones of mith's collection of 4634101 minimals (in the version cleaned up by you).
In order to get a large BxB classif for a minimal, starting from a minimal T&E(3) puzzle, one must most of the time get out of the solution grid of P.

Hi Denis,

I have been preparing a new batch of some 16 new B7B+ solutions. These would bring the new total in my local database to 820 B7B+ solutions.
Therefore I am very curious to compare with your two lists. However, the link you provided doesn't grant me access.

Hi Hendrik,
Sorry, I'm not used to google drive. I changed the permissions; it should work now.

Do you have any comment about most of the solution grids not being in the T&E(3) database?

Hi Denis,

I have not followed the recent developments concerning the T&E(3) puzzles closely. What I have noticed is that my scripts sometimes transform a T&E(3) puzzle into a T&E(2) puzzle via some intermediate transformations that change the solution. I gather that you have identified T&E(3) puzzles sharing the same solution with B7Bplus puzzles.
Could you give a concrete example of such a case?

I have compared your list of 781 B7Bplus solutions with my local database of 804 solutions published until 241223 (23 December 2024). The difference (23 solutions) are the ones in the hidden file, extracted from my local B7Bplus local database:

All my calculations are based on coloin's 4 "Mastermins" collections. I certainly miss the most recently found puzzles and those coloin didn't include in the "mastermins". I'll update them when you publish your new collection. What would be useful for me is a list of new B7B+ puzzles (possibly for the 781 grids) and of new solution grids.

[Added:] For the 1st of the above 5 grids, there are 22 B7B+ minimals:

Re: The BxB classification of T&E(2) puzzles

Postby hendrik_monard » Thu Apr 24, 2025 2:32 pm

Hi Denis,
As the 5 solutions with this 'overlap property' are coming from coloin, I was not directly involved in the generation process. That explains why it came as a surprise. Thanks for demonstrating so clearly this unexpected phenomenon.
My local database contains now the 781 in your list of yesterday, the 5 with 'overlap' in T&E(3), the 18 (23 - 5) published before 24 December 2024, missing in your list of yesterday but listed in my reply to your post of yesterday, and finally the 16 new ones below bringing the new total to 820 (781 + 5 + 18 + 16 = 820 ).
The following list contains 16 new B7B+ puzzles with new solutions. The twinning method has already been applied.
The puzzles are probably all min-expands. It is perhaps possible to find new solutions by combining 'higher' expansions and twinning.

Because these puzzles are not 'super' expanded, my script for obtaining minimals could find all 53 minimals:

With the following link the full list of the 820 B7B+ solutions can be downloaded. As the list is first sorted chronologically and then on x (in BxB), the new puzzles are at the end of the list. Next to the solutions, this list contains also the first published B7Bplus puzzle (the original isomorph!) with this solution, its publishing date and its x (in BxB). Please note that the 'early' original puzzles may have been published in the thread "The hardest sudokus (new thread)". Also the dates for the first 3 puzzles, coming from Champagne's database, may need correction.

I finally get 6259 minimals, corresponding to 781 different solution grids.

I think there are already 6259 minimal puzzles in total in the 4 files.. in 781 different grids... so no losses in your scripts !!
denis_berthier wrote:The most surprising point is, most of those solutions grids (653/781 Edit: 776/781) are not in the 67359 ones of mith's collection of 4634101 minimals.

As I remember some new TE3 puzzles came from BxB6 puzzles as a by product of generating and minimizing BxB6 [ removing a clue maybe to find a BxB6+ or a TE3]
However no BxB6+ ever were found by adding a clue to a known TE3 puzzle ... as we see not surprisingly

I thought I had discovered some more BxB6+ but I was mistaken, they are very rare.

I have expanded hendrik's recent posted puzzles and added 2 more twin grids.. [94 plus 109 minimals]
