I have this problem with GA toolbox 2.0 of Matlab 7.1 R14SP3.

When I run GA toolbox on a 32-bit CPU I always find the same
optimum solution for my optimization problem, while on a
64-bit CPU GA converges to different random values which
fullfill my constraints without trying to find the optimum one.

Is this a precision problem?

Should I change any of the GA functions or preferences to
face this problem?

Thank you in advance.
