I have a very long lasting optimization process (>100h) and I cannot wait until the end of that process. Nevertheless, I want to get the so far generated solutions (i.e. exact decision variables) of CPLEX. I am using the CPLEX Optimization Studio 12.6. Is this possible and if so, how?

Greetings!

Edit: I'm using OPL inside CPLEX Opt. Studio.

You can use a time limit

execute timeTermination {
    cplex.tilim = 3600; // maximum Runtime = 1h  
  }

OR you can use gap limit:

execute gapTermination {
    cplex.epgap = 0.05; // result at gap of 5%  
  }

for the optimization process to stop and output the results.

I added one of those limits on the top of my optimization program (OPL) in CPLEX.

This function is only available in Decition Optimization Center. You can stop optimization process and get generated solutions.
