Hi all,

my current MIP model is running for a very long time and I would like to look at some first feasible results. Initial research yielded that I can adjust parameters such as the MIP Emphasizer and the Optimality Gap. However, I cannot find information on how I set these parameters in OPL/CPLEX. And where could I access the solution pool? Can someone help? Thanks in advance!

Hi,

how to set a parameter in OPL ? You have an example in settings : options 1,2,3

in https://www.linkedin.com/pulse/making-decision-optimization-simple-alex-fleischer/

What you ask for :

execute
{
  cplex.epgap=0.01;
  cplex.mipemphasis=3;
}​

For the solution pool, see Get several solutions in the same set of examples I mentioned

NB:

You could also see the solutions in the IDE

regards
