got different solutions when running on Linux and Windows on R

[chinghoo]

Hi there,

I got different outputs from Rsymphony_solve_LP() using exactly the same inputs when my program running on Linux and Windows respectively on R.
Please be notified, this issue does not occur for most of the cases. However, it does occur for some inputs.

I am wondering does this package do the calculation differently on different OS such as Linux and Windows?

I have been struggling for this issue for a long time and would be greatly grateful if someone could answer my question!

Thank you!
Ching

When you say you got different solutions, do you mean different solutions of the (approximately) the same value? Or of different values? Can you post the output? In general, this would not be unexpected if the solutions have the same value.
