<div>I am currently using CBC to solve a large MILP</div>
<div> </div>
<div>The model has ~130K rows, 260K cols, 20K integers (all binary) and ~650K elements</div>
<div> </div>
<div>When we try to solve the model using cbc.exe it crashes. Basic exception handling code added to the tool suggests that CBC crashes with a bad_allocation error suggesting memory issues. the exe gets to about 1.8 Gb when it crashes. We are running this on
a box which has 16GB ram and at time of crash had about 50% of memory unused.</div>
<div> </div>
<div>Any suggestions on what we should do to solve this.</div>
<div> </div>
<div>FYI.. running it with dualSimplex option yields an integer feasible answer in ~ 1.5 hrs</div>
