<font color="#336666"><font size="2"><font face="verdana,sans-serif">Hi,<br><br>In the following code we try to take a subset of constraints using <i>MP_subset ( in the example: N)<br></i>I think the hard part is that in the same time we take a subset of data (in the example: Incoming and Outgoing)<i><br>
