Hi
I’ve found another run timeout error
on the f_1_1_1 put value=2
then f_8_9_9 put value=2 too

It leads me to error.. would you explain or fix it?

Thanks

There’s a link at the bottom of the post to the source code in PHP. Translation to Java should be easy enough!

…quick question not related to the sudoku but rather to php, are there any php video tutorials/awesome php books that you may recommend to someone who’s good at programming in java?

Nope, sorry — you could of course re-code mine, but it’s actually not very efficient in its current form, it prunes the branches a little late.

Any idea where I can find an efficient java source code for soduko?

Why when I enter my numbers and hit solve, does it timeout?

Unfortunately, there seem to be a few puzzles for which my algorithm is not ideal — in technical terms, it needs to do the “bound” part of the branch and bound algorithm sooner. I’ve thought of a few ways to achieve this … and then ran out of energy. Sorry. But it works for nearly all other puzzles.

This puzzle won’t solve because it times out with Firefox. Any suggestions?

I have a little Neopets help site and Neopets created the game Roodoku which is their version of Sudoku. I was hoping to find a free script that I could host myself for my visitors to use to solve the puzzles for them. I found the source code to this, but I’m not a programmer and can’t get it to work. :(

I’ve seen the online version though, and it’s a blessing!
