Samurai sudoku solving program

Hi there,

Having previously devised a program (VBA in excel) to solve conventional
sudoku puzzles, I have now developed a program that solves Samurai sudoku puzzles (ie the 5 interlocking grid puzzle). I am just wondering
whether anyone else have developed a similar program. It seems to solve
the most recent Samurais in the Times within about 10 seconds, using
a logic based algorithm. If there any programmers out there who would be interested in making it into a saleable product I would be happy to
hear from them.

I just adapted my 3x3x3 VB6 solver.
I just pull each of the 5 3x3x3 grids from the samurai in turn, partially solve them, then put them back into the samurai.
Takes a few iterations to converge - less than a second

Thanks for your reply.

Yes that is pretty much what I do, but in excel. I pass the information covering the overlapping sections from one grid to another. Because I have a slow pc and excel takes time to write to the cells its quite a bit slower though. I did find one site offering an online samurai solver, but you have to pay £1 to use it for a week. Its at http://sudoku.top-notch.co.uk/samurai.asp .
