No.

I have basically the tools to find them, but I never do it, it could influence the strategy applied to search a game pattern.

EDIT and more the decision to play or not a puzzle open to trumping

Having in hands

Code: Select all

     35 5.0/1.2/1.2
      9 5.8/1.2/1.2
      3 5.9/1.2/1.2
      1 6.0/1.2/1.2


which is the best strategy to decide the puzzle to play?

5.0 has most frequent. It has best chances to be enhanced to > 1.2 and is better to be delayed until stopping the puzzles generation.
On the other hand the less frequent ratings have better chances to be left undiscovered by the opponents.

right mladen, the good strategy seems to wait for a third party submission, but then, the quickest has a good chance to get the last entry bonus.

I have a 5.0 in cache,

may be after my nap if nothing happened

papy999 wouldn't be happy if you played for this reason

A use of a very simple robot enabled me this very quick answer
But it is not usable for the game !!!

I've nothing more... no trump, no self trump
For each ER I found an equivalent highest as played except the 2 diamonds 10.2 and 10.3
and nothing for 11.0 !

I think that dobrichev is the real winner of this game !

I stopped the search : only 1.7 million puzzles (valid, minimal, no morph)
As dobrichev said a very unusual pattern for the game but this seems normal for a 22 clues pattern

I'll send my potential hardest to champagne by pm

champagne 337 puzzles sent by pm (ER>=10.8 OR ER>=10.5 and pearl OR ER>=10.3 and diamond)
Patrice said there are 198 in your list
so there are at least 139 new ones and perhaps more

Tell me how many are new ones ...

In this game you, dobrichev and I found a lot of common potential hardest ... so who will you choose as author ?

this is not a key point. Mladen and me have already so many entries in the data base that some more are not so important.

Priority is to the first published status, so the priority is to the game
Then, I give priority to external sources, and as mladen did not send a file so far, your file will be processed first

BTW, for later use, the most important is to record when and where a puzzle has been published.

And I was not surprised to see that you have the skills for automatic submissions (this was the case for gsf and likely mike and patrice have such a tool). I have no skill at all in this field, one reason to work more in "search mode" for the games

Nope.
Maybe I had a better success/luck in the puzzles generation and rating, but your submission strategy in the last third of the game won.

You are the real winner. Congratulations!

I continued generation, the new puzzles rate drastically dropped after ~1.8M and now using some hacks few puzzles per minute are generated.
I did closure on -/+2 and for about 100K puzzles with various selected rating performed closure on -/+3.
So far the cache has 1985362 puzzles and my estimation is that > 98% of all puzzles are covered.

I too have no valid submissions nor self-trumps.

Many of the high-rated puzzles were passed trough serate so I can send them to champagne later today or tomorrow.
