Hi,

I'm new to this forum, so firstly - "Hello" to everybody! I must admit it's a pretty daunting forum for a newbie, with so much jargon & strange terminology Wink

Anyway, now i know my swordfish from my singles so i'm here to stay.

I've added my first stab at a solver on http://www.sudoku.uk.com I would appreciate any comments.

At the moment i look for naked singles, hidden singles, naked subsets (pairs, triplets etc.) and unit intersections. Got a few more to add. Also, there's only about 10 set puzzles, since i haven't got round to actually generating the puzzles online.

Regards,
Paul

to test your algorithm try these sudokus:

and mayber add a field where one can post a complete sudoku easely in such a format:

____8____
or
****8****

Thanks, will give them a bash. I do have a submit puzzle option (in .ss fomat). Just need to resolve some issues around hosting and security.

Source is not available at the moment, still go a lot of work to do! Surprised
