How difficult would it be to add Diagional puzzle solving to a solver? By Diagional Puzzle I mean a puzzle where cells that are located on the grid diagionals (from top-left to bottom-right, and top-right to bottom-left) must also only contains digits 1-9. I'm only thinking of solving them - not generating them. I'm thinking that it would be difficult, because the diagional puzzle structure would redefine what an X-Wing is, what Colouring is, what a conjugate is, etc... What do you think? Kranser.

The block/column/row interaction and x-wing techniques are still valid. best Bo Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         Sudoku Programmers Forum Index -> Exotic 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
