Martin,

On your home page you suggest that a 'sudoku work in progress' program, by Rob Haskell, has been added to the Xtra Software section, but it's not there! Or have I misunderstood?

Hi Pete,

Gosh, I've no idea how that happened. I could've sworn...

It's up now - sorry for the hassle. I'll mention it later on the homepage. Thanks for pointing it out.

Hi Martin,

At some time it was downloadable, cause I got it from here, but the last few days it seems to have been on vacation.... Laughing

It works fine now.

Helo,

Great, the sudoku OPL. But I use revo. Can anybody adapt the OPL for revo?

tanx!

Although I don't understand how to program in OPL, I succeeded in adapting the Sudoku OPL for revo by educated guessing which numbers I had to change, and trial and error.

So I've sent Martin the adapted version. If the other of the original OPL agrees, this can be put on your site.

I tried the OPL, and in fact, I'm a bit disappointed. It's marvelous how people manage to program things like this, but I found the same pattern in all generated Sudokus by the OPL:
DON'T READ FURTHER IF YOU WANT TO USE THE OPL FOR GENERATING SUDOKUS TO SOLVE YOURSELF!!!

- In the first row, all parts of 3 cells (colom 1-2-3 or 4-5-6 or 7-8-9) contain one of the following sequences in mixed order: 1-2-3 or 4-5-6 or 7-8-9
- Idem in the second and third row
- In the 4th to 6th row, the sequences are 8-9-1 or 2-3-4 or 5-6-7 in mixed order
- In the 7th to 9th row, the sequences are 9-1-2 or 3-4-5 or 6-7-8 in mixed order

I guess it's very complicated to make the OPL make really random Sudokus

I've been searching for a sudoku maker for epoc that doesn't create sudokus with some kind of regular pattern, but I couldn't find one. So I tried something myself. I made a sheet that generates sudokus with a regular pattern. I've send it to Martin. He will decide wether it's something for pscience5 or not.

The sheet is not a program: a few key presses are needed the generate a new sudoku. Also, the sheet is not able to generate all possible sudokus, but "only" a few quadrillion (so, still endless, but from the programmers point of few: not perfect).

An OPL program is much nicer, but I can't program in OPL.
OPL sudoku is nice, but doesn't contain the right algorithm for creating random sudokus. Some java and visual basic programmers know a good algorithm that must be possible to be used in OPL sudoku. Who can help?

In the main time: sudoku epoc sheet will have to do.

Hello,

I am fan of Sudoku game.
I edit my own Sudoku website.

I have seen your discussion and I am interested in it.

But what is Sudoku OPL ?

I'm not sure if you own a Psion but I guess not. Sudoku which is placed on this site is a small program for this PDA-Machine. OPL is the developement language in which this program is written.
You won't be able to run it on your PC in case you don't want to use an emulator...

Thank you Jonas for your response.
I develop a little bit and i don't know OPL.

I look for an OPL (optimization programming langage) file with extension .mod to resolve a Sudoku problem.
Do you have it please ? Do you know where I can find it please ?
In fact : How to programming Sudoku in OPL langage

Thank you very much

OPL is Open Programming Language.
I am not sure what you really want, do you own a Psion?
Soduku from here is a program for EPOC 32, not Windows etc...
