I have difficulty with solving the single 9x9 case. I too wrote a program to solve Sudoku puzzles. My program is in C with a recursive implementation of a brute-force with backtracking method. Not so clever or exciting but I like how programs can solve problems.<br /><br />What turned out to be interesting for me is how I applied my Sudoku solver to generate Sudoku solutions boards (starting with a blank board) from which I generated Sudoku puzzles for my website http://this1that1whatever.com/miscellany/sudoku/.<br /><br />Now I&#39;m getting more interested in learning ways to solve Sudoku with my own brain. However, I need to spend time on building my website.Davidhttp://this1that1whatever.com/miscellany/sudoku/noreply@blogger.comtag:blogger.com,1999:blog-6406593750327945950.post-49149393480623084822008-01-29T16:24:00.000-08:002008-01-29T16:24:00.000-08:00Nice, will check your code later. The thing I really like on sudoku is how difficult you can get without the need of pen and paper - keeping all the numbers in your mind. That's when it gets really interesting.kyughttp://www.blogger.com/profile/07742525511396500066noreply@blogger.com
