| I'm not sure if this project is still active but I have recently developed it further to include 'X-wing' solutions of order 2, 3 (swordfish) and 4 (jellyfish). I've also fixed a problem that occurrs in php 5.2.8 due to changes in the _to_string operation. I'm not sure how to post the code here but I can email it to the author if interested. It still does not solve the 'hard' example but it now solves everything in 'Extreme Sudoku' by Wayne Gould. |

Hi Mike,
This is the true spirit of open source!
Yes, I would like to post your new version!
Please send it to me and I will do that.
I did not look at the package for quite a while, it is a hobby project after all. But I am still planning to do also the last resort: brute force tree walking, so that it can really solve every puzzle. But I still think that its solution strategy should be humanly understandable, therefore brute force is not really interesting.
Cheers, Ghica |

Hi Ghica,
Did you get my new code? I sent it to the email address you have on this site.
I have been extending the program further to include XY and Single Chains. The XY Chains now mean the hard puzzle can be solved logically.
Mike

Yes, I got your code. I will post it, but I first wanted to try it out.
Cheers, Ghica. |

The new code has been posted. Works great! Thanks for the good work Mike.
I hope this will inspire me to fresh-up the UI a bit. |
