Dear GouinJP,
Please note that the current game is closed. A new one will start on Sunday evening (European time). Please note also that the point of the Game, like many card games, is to play a higher rating than that of the opponents.

OK it's fun, I will be there.

How many puzzles can I submit in one batch?

Could you explain? blue submited an ED=2.3/2.0/2.0 just before it closed. That's not very good!

I noted that SudokuExplainer is very slow. What can I do?

Thanks for stimulation.

Hi GouinJP,

First of all, many of your questions could find an answer in that thread where you could have posted your questions
patterns-game-strategies

How many puzzles can I submit in one batch?

If you are thinking of "serate batches", there is no limit, but as you say, it is a very slow process, so the main points is what to do to rate less puzzles.

Could you explain? blue submited an ED=2.3/2.0/2.0 just before it closed. That's not very good!

Each serate ER is a separate entry.
The trumping rule applies entry per entry.
It's very common in a game that players submit in priority high diamonds and / or rare ratings.
During the last part of the game, you find usually entries with no diamond generated and this can be on the low ED's

I noted that SudokuExplainer is very slow. What can I do?

At the start, just accept it, but if you want to do more, you must have tools to select interesting puzzles and submit to serate only puzzles having a chance to be of interest at the currenr point of the game.

You should find many clues if you follow the link

It was Pat, actually, and it was good for the "last-entry" bonus.

puzzles for the game must be minimal

* when you do get a minimal puzzle,
it should be posted on 9 lines
and inside [code]

Pat, This puzzle, is minimal, it's simply the pattern of the previous game.

Hello

I found 2 000 000 valid puzzles for game 215 but I can't rate them all with SudokuExplainer.

What is the good stategy?
Before final rating with SudokuExplainer, I must choose the good candidates rating them with gsf's sudoku or with skfr?

Thank you

Jean-Pierre, You can probably use either (I use neither), but I think most of us try to reduce these huge numbers by supressing low ratings at birth. This requires, I think, a certain amount of coding of your own programs (or even a lot of coding).

skfr has been designed to be close enough to serate to help in the pattern game, it is about 100 times faster than serate, but the deviations are sufficient to say that the final validation by serate is compulsory.

The deviation in the rating is most often +-0.1, but can be wider;

I have no personal experience of gsf's sudoku.

In the last games that I searched, I used my last program, skmpp, faster than skfr and performing better in the way I played , but I generate many more puzzle in a game (say 50 to 100 million puzzles for a pattern as in the game 215)

One difficulty is in the fact that at the beginning players are looking for a fast show of diamonds. Later on, you have to play in the holes. Then, you need more or less a pre rating of all puzzles.

My suggestion would be (as did dobrichev) to pre-rate all puzzles unless you really want to win the game, and then to filter the puzzles to rate in serate.

Increasing the chance to win the game push to use a more complex strategy.

Hi everybody

Instead of compete in this patterns game, it is also possible to participate together and share the game in different searching spaces.
For instance, in the game 0169, only 24 puzzles were posted when gsf wan with a beautiful ED=11.8/11.8/3.4.
001000200090008050600000007000003040000020000080905000700000006050400030002000100

If I canonise this puzzle, it gives :

You can see that nobody submits a puzzle begining with:
001000200030002000000000000000000000000000000000000000000000000000000000000000000

Maybe sharing our work, we could revisit old neglected patterns game and beat the famous ED=11.9/11.9/11.3.
Why not enter the Guinness Book of Records together?

Jean-Pierre,
You've picked a bad example with Game 169. It has already been extensively discussed in the Strategies thread, starting on 'Tue Mar 13, 2012 8:52 pm'. Note, too, that the pattern is an isomorph of a pattern published on 'Wed Feb 07, 2007 6:11 pm' here and also in the General (I think) Forum at that time (I don't have the time to search further just now), where it was also discussed. The puzzle has a high degree of symmetry of givens.

Here are the two canonised patterns for the hardest sudoku and the best post for game 0169.
If I remember, champage said he can guess which ED can be hoped with a given pattern.
Could we focus on a pattern close to the best pattern ?

... and also in the General (I think) Forum at that time (I don't have the time to search further just now), where it was also discussed.

It was on Wed Feb 07, 2007 6:15 pm starting here. This pattern has been done to death.

Hi

Look these canonised patterns.
000001001000010010001000101001000010010010001100100100001001010010010100100100000 the famous ED=11.9/11.9/11.3.
000001001001001010010010100001001010010010100100100001001001010010010100100100001

The second one is the closest pattern found in all 220 games in this forum. It seems to me we could search hard sudokus with pattern nearest than the hardest one.
But I prefer to play than to suggest patterns.

Question concerning the rule against self-trumping: If I post a puzzle, and someone trumps me, can I then trump him, or does that break the no-self-trumping rule because I already posted a puzzle with that ER?
