Hi, Pat!
Thank you very much for your help! I've successfully downloaded sudoku.exe for Windows. It works fine!

the above example assumes you have set up a file specifying the desired layout

layout.TXT — example — 21 cells given (layout 180 of the Patterns Game)

Code: Select all

. O . . . O . . O
O . . . . . . O .
. . O O O . . . .
. . O . . . . O .
. . O . . . . . .
O . . . . O O . .
. . . . . O O . .

    the way i wrote the example,
    it just keeps generating puzzles;
    i suppose you stopped it eventually (e.g. Ctrl-C)
    — did you look at the contents of puzzles.TXT ?


    or you could add an option restricting the number of puzzles —

      sudoku -gt -n20 <Layout.TXT >Puzzles.TXT

How are you getting the "command prompt window?" Double-clicking on sudoku.exe in the explorer window won't work. You have to first separately launch the Command Prompt window.

Telkin,

under windows i make batch files to use gsf's program. You then just can double click on them in the explorer to start it.

For Pat's example you can start notepad (click start and enter "notepad") and copy Pat's pattern there. Then save it in the directory, where you have gsf's sudoku.exe as layout.txt.

Open a new notepad and copy there:

sudoku -gt < layout.txt > generated.txt

Save this as generate.bat in the same directory.

Then go to this directory in the explainer and double click on this generate.bat. (With a right click you can select to change it)
A black cmd.exe window (the same you get when you click start and enter "cmd") will pop up saying:
<path>\sudoku -gt 0<layout.txt 1>generated.txt

After some minutes you can find generated puzzles, when you open generated.txt in this directory.

You stop it by typing CTRL+C into the cmd window - or just close the window.


Note, that in the batch files you have to type a double % sign instead of a single one directly from the command line.
E.g. to canonicalize a list of puzzles instead of
sudoku -qFN -f%#0c %#0v "%i" puzzles.txt > canonicalized.txt
write into the batch file (say canonicalize.bat)
sudoku -qFN -f%%#0c %%#0v "%%i" puzzles.txt > canonicalized.txt

I have just tried some of gsf's other commands with no success, but thank you for this, I am now able to generate puzzles of different parameters, but would also like to generate puzzles for the hardest sudoku thread, how would I do this.

I remember we had a micro-sd circulating by snail-mail
with the code and all the data
(when was that, maybe I search it later)

Hi

It would be a better idea to send a DVD with all the 5472730538 essentially different solution grids because the micro-sd contains all .sudz files, not extracted.
