Re: [xsl] A new Sudoku xslt implementation

Hi Dimitre,
  In my application I am using a 3rd party library for finding a
cartesian product of any number of sets(with any number of elements in
each set). The relevant line in source code is Collection cp =
Setops.cross(sets); I guess the 3rd party library is quite resource
hungry. I have not been able to write a similar (and efficient)
algorithm in short time. I guess this is probably the reason of
OutOfMemoryError error.

I am working to improve the efficiency of my application. I would be
grateful if anybody could give any ideas. Probably you could!

I observed that my application works for simple Sudokus.

Regards,
Mukul
