Hi,

 

my model is ready for run, I have about 200 products and 150 suppliers. This results in rather big input matrices. The problem is, when I run Xpress,  at first nothing is shown in a tab "Stats". I found out that data are shown there when Xpress reaches the objective function. Am I right?

 

Besides, this is what is written in the tab "Stats" now:

 

 

Althoug Xpress says that the model is still running, I have a feeling that nothing is happening. I mean the value of the free memory in the bottom right corner is not changing and I cannot see the BB tree.

 

Can you explain me what is happening? Might there be a mistake?

 

Thank you!
