[Coin-symphony] Fix the variables

[Yossiri Adulyasak]

I am doing column generation using Symphony and CLP solver.

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.


But to do that, I need to get dual/shadow prices from that RMP IP solution.


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.)

Anybody can give me some ideas or suggestions.

Thank you for your time.
