<div>I am doing column generation using Symphony and CLP solver. </div>
<div> </div>
<div>I first try to solve the Restricted Master Problem to IP optimal, then I would like to use the reduced cost from that solution to price the columns. </div>
<div> </div>
<div>But to do that, I need to get dual/shadow prices from that RMP IP solution. </div>
<div> </div>
<div>I can't seem to find a way to fix the variables to the IP solution (so that I can use CLP to solve it as LP-fixed.) </div>
<div> </div>
<div>Anybody can give me some ideas or suggestions. </div>
<div> </div>
