<font face="arial,helvetica,sans-serif">Hi,</font><div><font face="arial,helvetica,sans-serif"><br></font></div><div><font face="arial,helvetica,sans-serif">I'm trying to integrate my cut generator with CGL.</font></div>
<div><font face="arial,helvetica,sans-serif"><br></font></div><div><font face="arial,helvetica,sans-serif">My cut generator uses information of the implicit conflict graph of binary variables. Since I try to lift these cuts, including variables which are not active (=0) in the current fractional solution, I maintain this large implicit conflict graph which is built at the beginning of the search process.</font></div>
<div><font face="arial,helvetica,sans-serif"><br></font></div><div><font face="arial,helvetica,sans-serif">To avoid the expensive work of rebuilt this conflict graph at each generateCuts call I would like to keep it stored in my CglCutGenerator derived object - updating it would be a lot faster than reconstruct it. However I'm not succeeding in update any information in this class since the method has a const modifier.</font></div>
<div><font face="arial,helvetica,sans-serif"><br></font></div><div><font face="arial,helvetica,sans-serif">Any tips on how can I solve it ?</font></div><div><font face="arial,helvetica,sans-serif"><br></font></div><div><font face="arial,helvetica,sans-serif">Cheers,</font></div>
