Does anyone have the solution to ruuds killer sudoku, on his killer solving guide: http://www.sudocue.net/killerguide.php The one I'm looking for is Innie and Outie practice. My solver, which I have only just made seems to think its unsolveable. In ruud's killer sum calculator he allows more than one of the same number in each cage. My program won't allow this, so i just wan't to check to see if its an error with my solver.

I managed to make a 9x9 full grid on paper without any mistakes, then I tried 16x16, it took quite a bit longer, but when I got near the end I found a mistake I made right near the start, I'd put 2 11's in the same column. But I think it is quite easy to program it into my program. Have you got any sizes above 9x9 working yet?

Sorry, but i have to disappoint you. The 9x9 jigsaw works fine, well, most of the time it will fill a grid in an acceptable time. The 12x12 works, but you have to be very, very lucky for a filled grid in a reasonable time. The 16x16 is still a disaster for filling the jigsaw grid, but i'm pretty satisfied for generating regular 16x16 sudokus with it (the 16x16 just like the 9x9 has that option, the 12x12 doesn't). _________________ Marc ~~~<><~~~<><~~~<><~~~<><~~~ Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         Sudoku Programmers Forum Index -> Solving sudoku All times are GMT Page 1 of 1   Jump to: Select a forum Sudoku----------------Solving sudokuSetting sudokuProgramming sudokuThe mathematics of sudokuExotic sudoku Library----------------PuzzlesSoftwareSudoku elsewhere Not sudoku----------------Random thoughtsForum feedback  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum   Powered by phpBB © 2001, 2005 phpBB Group Igloo Theme Version 1.0 :: Created By: Andrew Charron
