Your Java code doesn't seem to have a lot to do with the C++ code, e.g. where
do you use X, and what does the last line mean? If you want us to help you,
you'll need to provide code samples that we can understand. The gecode code
doesn't look much better, e.g. what is IntArgs(n*m,0,1000000) supposed to mean?
That will allocate an array of size n*m and initialise the first two elements,
but the rest will be uninitialised (probably random).
Cheers,
Guido
