Hello,

Is it possible to get a copy of the contest puzzle from September? Any version will do -- even a screenshot of it. Here's why I am asking.

I wrote a SuDoKu-solving program (who hasn't?). Every time I've tested it (i.e., I manually solve a puzzle and I enter it into the program and I compare my answer to the program's), the results match. Last month I submitted a solution to the September puzzle, and according to today's http://www.sudoku.com/contest.htm web site, my answer was wrong. This means the program I wrote (in which I have -- had!? -- confidence) got it wrong. This is why I would like to see the puzzle again.

The program I wrote (I allege) uses logic, no guessing. It, in fact, cannot "solve" some of the "most difficult" puzzles posted here. I checked with the downloadable program (this web site), and it could not "verify" these same puzzles either. My attraction to SuDoKu has to do with whether logic only can solve a puzzle, and whether any exclusively logic-using sequence will arrive at the same unique solution. (I could probably formalize that, but I think anyone reading this knows what I mean.)

Regards, and thanks.
