Congratulations TTHsieh,

I don't think I will be able to defeat your ER=9.0
This 20 clues pattern is not easy and you found lots of different ER ratings though.

Nice work

by **TTHsieh** » Mon Aug 13, 2007 3:34 pm

Puzzles of the pattern:
1. most ERs concentrate in 1.2, 1.5, 2.0, 2.6, about 80%
2. difficult : 2.3, 2.8, 3.0, 3.2, 3.4, 4.5, 4.6, 8.4, 9.0
3. the most difficult : 4.2, 8.8

JPF's new rule wrote:Points : when a puzzle is posted the player gets points = # posted puzzle.
i.e : the dealer gets 1 pt, next puzzle 2 pt, etc...

Fills in the gap may obtain how many points ?

Thanks ronk for the nice summary.

Here are the tentative scores with the proposed new rules.

B = better ER
B*= best ER
G = gap

Code: Select all: Player # ER B/G Points TTHsieh 1.2 B JPF 1 2.0 B 1 TTHsieh 2 2.6 B 2 TTHsieh 3 1.5 G 3 TTHsieh 4 1.7 G 4 JPF 5 2.5 G 5 TTHsieh 6 2.3 G 6 JPF 7 3.4 B 7 TTHsieh 8 2.8 G 8 TTHsieh 9 3.0 G 9 TTHsieh 10 3.2 G 10 TTHsieh 11 4.4 B 11 JPF 12 5.6 B 12 TTHsieh 13 4.2 G 13 TTHsieh 14 4.5 G 14 TTHsieh 15 4.6 G 15 TTHsieh 16 6.6 B 16 JPF 17 6.7 B 17 TTHsieh 18 7.2 B 18 JPF 19 8.3 B 19 JPF 20 7.1 G 20 TTHsieh 21 6.9 G 21 TTHsieh 22 7.3 G 22 TTHsieh 23 9.0 B* 23 TTHsieh 24 8.5 G 24 TTHsieh 25 8.4 G 25 TTHsieh 26 8.8 G 26 351 Scores : JPF 81 TTHsieh 280 (including 10 pts bonus)

The proposed puzzles don't need to be by increasing ER.

A bit complex though

hm... any comments ?

This is a good idea for collecting complete ERs.

How do you extract SE rating from a file(windows mode)?

This 20 clues pattern is not easy ...

Any other ER? if not, Let's start next challenge earlier, agree?

From here:
java -cp SudokuExplainer.jar diuf.sudoku.test.Tester sudoku.txt result.txt
You can copy it to a batch file, e.g. ER.bat and start it with a double click.

OK, but please note the limitation of the number of puzzles which can be proposed :

JPF wrote:Each posted puzzle must have a new ER and has to be minimal.
First post (dealer) = singles
other post = 2 puzzles max, say for 2 days, except if an other player posts a puzzle.

The game ends if no puzzle has been posted for 1 week.

Points : when a puzzle is posted the player gets points = # posted puzzle.
i.e : the dealer gets 1 pt, next puzzle 2 pt, etc...
At the end of the game a 10 pts bonus is given to the higher SE rating.
