Hi all,

My name is Darren, i'm a final year Software Engineering student from Belfast. I have written a Sodoku Solver in java, with an interface in swing. I have only managed to implement techniques up to Naked Triplets, which is pretty feeble i know!

However, i was just wondering, do any of you know where i could find a text file full of puzzles that would be solveable with techniques up to Naked Triplets? I have a button in my interfce which takes puzzles from a file and displays them to the user to play, but these need to be solvable if the user gets stuck!

Appreciation in advance,
Darren

Hi Ruud,

Thanks for your reply! I would probably need a minimum of around 200 puzzles or so, but anything over that would be welcomed Smile

Here is a collection of 250 that need no more than naked triples:

Paste them into a text file and have a go.

Good luck,

Ruud.

Edit: A few heavier sudokus removed from the list.

Ruud,

That is fantastic, exactly what i needed and even in the right format! Thank you so much for your help! My project demo should now look a bit better Wink

And also to say, i have played around with Sudo Cue, it is fantastic. I have also had a play around with Simon Armstrong's and Bob Hanson's solvers, the stuff i aspire to! It is only really when i tried to do this that i realised how tough it is, although my programming is not the stongest.

Respect, and many thanks,
Darren

Here is a collection of 250 that need no more than naked triples:

these seem to need more
the first two x-wing + x-cycle (or coloring), the rest x-cycle (coloring)
numbers in "..." are the ordinal within the 250
the puzzles are in the state near where x-wing/x-cycle seems to be required

Thanks for performing the QA check Smile

These must have slipped through the net. I have removed them from the list.

Thank you once again for your help with the list of puzzles a couple of weeks ago! I now have my solver online. And my project is due on Friday! I have one more request, as part of formally testing the modules of my solver.

Do you have puzzles stored that require certain methods to solve them? That is all techniques up to that standard. The categories of puzzle i am looking for are:

Single Candidate
Hidden Candidate
Block / Row / Column Interactions
Block / Block interactions
Naked Pairs
Naked Triplets

If you had between 5 and 10 of each type of puzzle, it would be really appreciated!

Thanks,
Darren

hi all

the link Ruud has kindly posted appears to no longer be operational,
as such i'm asking if anyone knows a different link to Ruud's benchmarking list, or has a copy they could send me to test my solver!

thanks in advance!

Replacing "www.sudoku.com/forums" with "forum.enjoysudoku.com" will usually work.

Be aware that many new techniques have been developed since 2006.
