<div><span class="260160604-28102009"><font face="Arial" size="2">I've been testing Cbc with Clp to solve transport assignment problem, normally I use Cplex.</font></span></div>
<div><span class="260160604-28102009"><font face="Arial" size="2">Cbc works fine on smaller versions of the problem but when I use it on the full size problem, it seems to hang after a while.</font></span></div>
<div><span class="260160604-28102009"><font face="Arial" size="2">The same problem solves fine using Cplex.</font></span></div>
<div><span class="260160604-28102009"><font face="Arial" size="2">You can download the mps file from this location (it's a 2.6Mb zip file, I was not sure how to upload it to the mailing list so I've put it on my website):</font></span></div>

<div><span class="260160604-28102009"><font face="Arial" size="2">I solve this using the sample2 code with the preprocess option turned on, when I don't use the preprocess option it solves for a bit longer but eventually hangs as well.</font></span></div>
<div><span class="260160604-28102009"><font face="Arial" size="2">Thanks in advance,</font></span></div>
