How regular is to generate sudoku with difficulty 9+ SE?

Everything about Sudoku that doesn't fit in one of the other sections

And one more 10.5 that I found while looking at some of the lower gsfr puzzles from my previous search:

10.5 # 1...5......67...2..8...3..........9...4...2.6...2..3415...1.....3...8.....76....4 # RW 04/04

gsfr only 99648...

Thanks JPF for collecting the new toughies. Maybe there indeed would be need to either update the existing thread (if ravel is up for it) or start a new thread to collect all these nice puzzle.

Nice work too JPF. Not so many large SEs as I was expecting - the suexrat9 program had a big tendancy to miss strong puzzles.....however I do have another 11.2. At present Im updating the SE on The St.Patrick puzzles.

I have used a program refered from here from the forum here

which has a useful and quick ratings program - although possibly not consistant with isomorph puzzles.

It does however rate St.Patrick-6 ever so highly despite a SE of 10.7

Confusion with the equivalent forms and different forms of a 16-clue base might now be resolved - there are up to 8 variations - is it the reflective symmetry which reduces this in this 16-base to 4 plus 4-different of each pattern.
Code: Select all
5.......9.2.1...7...8...3...4.......................1.3.....8...6...4.2...9.....5
5.......9.2.1...7...8...3...4.......................1.9.....8...6...4.2...3.....5
5.....9...2.1...7...8.....3.4.......................1...3...8...6...4.2.9.......5
5.....9...2.1...7...8.....3.4.......................1...9...8...6...4.2.3.......5

5.......9.2.1...7...8...3...4.......................1...9...8...6...4.2.3.......5
5.......9.2.1...7...8...3...4.......................1...3...8...6...4.2.9.......5
5.....9...2.1...7...8.....3.4.......................1.3.....8...6...4.2...9.....5
5.....9...2.1...7...8.....3.4.......................1.9.....8...6...4.2...3.....5

414054 sol.
414054 sol.
414054 sol.
414054 sol.
529148 sol.
295376 sol.
546052 sol.
295208 sol.

It is highly likely that bases with same number of solutions are equivalent.

Least number of grid solutions I found
Code: Select all
1.......9.2..4..7...3...5............4.....8............5...3...8..2..4.9.......1
108864 sol.

Which gave us a 19 clue - not with the diagonal
Code: Select all
SE 9.2 1.......9.2..4..7...3...5.......5....4.....8.....32.....5...3...8..7..2.9.......1

I also include these two already published from the hardest forum

11.1 # 5.....3...2.1...7...8.....9.4...7......821......6...1.3.....8...6...4.2...9.....5 # coloin 03/22 [295208#1]
10.8 # 5.......9.2.1...7...8...3...4.2.7.......3........46.1...9...8...6...4.2.3.......5 # coloin 03/22 [529148#1]

Let me know if its any of you think its worth classifying them this way.
Perhaps to avoid confusion in these cases we should defer the canicalizing for later.
Isomorphs will have the same SE and 16clue base - but can be certainly differentiated by having a different index416.

Michael Deverin posted a row order min-lex canonicalizer in the programmer's forum
in January that works on puzzles with multiple solutions
(the canonicalizer in my solver works on solution grids only)
I ran it on the 8 templates and indeed the ones with the same number of solutions are isomorphic
so the templates boil down to
Code: Select all
5.......9.2.1...7...8...3...4.......................1...3...8...6...4.2.9.......5 #  295376
5.......9.2.1...7...8...3...4.......................1...9...8...6...4.2.3.......5 #  529148
5.......9.2.1...7...8...3...4.......................1.3.....8...6...4.2...9.....5 #  414054
5.....9...2.1...7...8.....3.4.......................1.3.....8...6...4.2...9.....5 #  546052
5.....9...2.1...7...8.....3.4.......................1.9.....8...6...4.2...3.....5 #  295208

My first SE9.3 is found

Postby Morgoth » Thu Apr 05, 2007 11:37 am

My doubts were true. There was a bug in my generator and some of the puzzles were not minimal, that's why it was not possible to produce puzzles harder then SE 9.2. I found it using one of the examples from here as a base - it didn't succeed to found it - all puzzles were at least with one more candidate.

After fixing I found it in first 500 puzzles. For pity the fix dramatically decreased the performance, so I need to spend some time for optimizations. After that I'll be also able to find 10+:D

Keep it up Morgoth !

Thanks for the verification on the 16base grids......have you tried to tabulate the ones with sol. < 1000000 ?
e.g.
Code: Select all
+---+---+---+
|1..|...|..6|
|.2.|x..|.5.|
|..3|...|4..|
+---+---+---+
|yyy|...|...|
|...|...|...|
|...|...|...|
+---+---+---+
|zzz|...|3..|
|zzz|...|.2.|
|zzz|...|..1|
+---+---+---+

x is not 123456
y is not 123 or z
z is a diagonal but not 123 or y
single clue in box 6 and 8 - not 123
Are there really too many ?

Here are the surprizing data from the StPatrick base run....filtered initially with suexrat........

It's up to ravel to decide.
What about "The hardest sudoku – Vol. 2" ?
I will update the list with the last posted puzzles.

Why am I not surprised... This technique really reveals insane amounts of hard puzzles! Here's another goldmine I found:
Code: Select all
 *-----------*
 |1..|...|..6|

 |..3|...|4..|

Same as the one Mike's 11.4 came from, but r7c7 and r9c9 swapped. Explainer is currently chewing at the 20 gsfr 99990+ puzzles in the pattern. Here's 43 more with gsfr 99800-99900 if someone is interested:

[edit: gsf, I just noticed the 'G' in the constraints listed for the 99990+ puzzles. Does this mean that your solver cannot solve them with nested propositions and has to guess?]

[Edit 2: ravel, I'd be very interested to see how many steps your solver needs for this one:
Code: Select all
1.......9..67...2..8....5......6..7....3.8.....427.....9....8..5.......1..2.4..3.

ER 11.2, lots of forcing chains:

JPF and RW,

congrats on your new toughies (i am curious about RW's hardest).

JPF wrote:It's up to ravel to decide.
What about "The hardest sudoku – Vol. 2" ?
I would appreciate very much, if someone else would administrate a follow-up thread. To be honest, i am really a bit tired of it, though just now we have exciting new aspects.

So all i planned, was to wait, what the next week will bring and then update the top lists. It will be easy, when JPF continues his work:)

I will rate RW's puzzle tomorrow, but over Easter i cannot run my program.

These are my top ratings with "solution path" for the symmetrical puzzles in this thread.
Note that (to save time) in the first run i only try to eliminate candidates, that (with the implemented technics) immediately lead to at least 2 more eliminations. In the second run also those with 1 additional elimination are tried.
Only for those with a rating >17 in the first run i made a second run.

As you already noticed, the ratings of this program are inconsistent for isomorhps. For 10 scrambled versions of your puzzle i got ratings between 2814 and 5439, for another one (ER 10.8) between 2678 and 5834. So the correlation to itself is worse than the one between gsfr and ER:)
