Pinned topic How is increase the 'Best node' converging speed?

‏2013-04-24T01:59:36Z |


I am using the Cplex OPL IDE 12.5. I have a problem with my MIQP model, all variable are the binary type. 

From the Engine log, I can see the optimal value has already found in the 'Best integer'.

The optimal value is already known and apply here only for the model testing propose.

However, the converging speed of the red line, which is Best node is extremely slow.  Is there any way to speed up?

And there is no gap information in the log. So strange.
