Has anyone come up with a standard puzzle definition format for jigsaw sudoku (similar to the 81-character line format for standard sudoku)?

I'm a little confused. How does that second format translate from a killer jigsaw to a vanilla jigsaw? And I've long since forgotten what format is referred to as PS. Can someone enlighten me on both points?

[enxio27]

After further investigation, I think the answer to my question is "SumoCue" format, but I don't understand how the format works. I'm hoping to figure out a way to convert a jigsaw puzzle image into that format without having to do it by hand.

(This is no valid jigsaw, just a format demo.)

Hmmm. . . That one actually makes sense, although it's somewhat longer than the SumoCue, and it could theoretically be reduced to two 81-character lines (or one 162-character line). Do you know whether any sudoku software imports or exports this format?

Is this your idea, or did you find it somewhere else? (I want to propose it on another forum, but I want to give credit where credit is due.)

My own program uses this. This way it was easy to program.

Do you use it in the form you show above, or do you reduce it?

Currently I don't reduce it - my formats consist of 9 lines as I posted.

Ok, thanks. I've proposed my reduced-size version to Richard Broughton for support in his SudokuSolver program, with credit to you for your original concept, of course.
