non isomorphic to the previous posted.

add this new rule and keep the first posted will solve the problem.

I agree.
This new rule has been added and will be applied for the next pattern.
Your 2 ratings ER 8.9 and ER 8.5 are OK for this game :

Code: Select all

ratings : 1.2 - 1.5 - 1.7 - 2.0 - 2.3 - 2.5 - 2.6 - 2.8 - 3.0 - 3.4 - 3.6 - 4.0 - 4.2 - 4.4 - 4.5 - 4.6 - 5.6 - 5.7 - 6.6 - 6.7 - 6.8 - 6.9 - 7.0 - 7.1 - 7.2 - 7.3 - 7.8 - 8.5 - 8.9

Current score :

I find this puzzle with ER=7.7, but it's not a minimal.

Code: Select all

 . . 3 | 4 5 6 | 7 . .
 . . 9 | . . . | 1 . .
 . . 4 | . . . | 2 . .
 - - - + - - - + - - -
 . 6 . | . . . | . 2 .
 2 . . | . 1 . | . . 8
 . 3 . | . . . | . 4 .
 - - - + - - - + - - -
 . . 6 | . . . | 5 . .
 . . . | 3 . 2 | . . .
 . . . | . 8 . | . . .   ER=7.7



In my empirical evidence, this pattern is hard :

• hard to genarate puzzles.
• hard to find difference ratings, over 93% concentrate in 1.5, 1.7, 2.0, 2.6

Up to now, Points of this game: 233(TTH) - 232(JPF) = 1
JPF, You are a strong competitor.

I'm giving up, congratulations TTHsieh

Here the final score including bonuses and penalty.

Code: Select all

ratings : 1.2 - 1.5 - 1.7 - 2.0 - 2.3 - 2.5 - 2.6 - 2.8 - 3.0 - 3.4 - 3.6 - 4.0 - 4.2 - 4.4 - 4.5 - 4.6 - 5.6 - 5.7 - 6.6 - 6.7 - 6.8 - 6.9 - 7.0 - 7.1 - 7.2 - 7.3 - 7.8 - 8.5 - 8.9

Final score :

             Points     Bonus     Total                                         
  TTHsieh       233     20+30       283                                         
      JPF       232       -20       212


JPF, You are a strong competitor.

Thanks, you are not bad yourself too

Some remarks following the study of this pattern :

• bug in S.Explainer as RW analysed
• strange divergence between ER and gsf's rating (gsfr) : my best gsfr score was 95164 (ER=7.2) with this one :

  Code: Select all

  001234500003000600004000700080000040700050009020000070007000100000608000000010000

  
  The best ERs (8.9 and 8.5) have only gsfr 9278 and 17470 respectively, as I mentionned before.PS : In order to allow more people to participate, it would be wise to limit the number of posted puzzles to one, instead of two, for 2 days ?

In order to allow more people to participate, it would be wise to limit the number of posted puzzles to one, instead of two, for 2 days ?

It is a good idea.
My suggestion : Each player can post 1 puzzle for 1 day, except if somebody posts an other satisfactory puzzle.
Hope to see Mauricio, ravel, ...
