Hi John<br>
<br>
After solving a MIP problem with CBC, does it automatically solve a post-MIP LP with the integer variables fixed to the MIP solution values so we can extract meaningful duals of the binding constraints?<br>
<br>
It looks like you can with CBC, although some of the commercial solvers require you to explicitly solve an LP with their integer variables fixed.<br>
