How to use 'IloOplOutputFile' in Cplex to write variables with more than one index?

I am trying to write the result data to an external file because of an error I got after running the code for 16 hours.

I found the code above, it works for the variables with one index but my variables are not with one index. There are even variables with 4 indexes. How can I adapt this code to my situation?

execute{
  var ofile = new IloOplOutputFile("modelRun.txt");
  ofile.writeln("Data:");
  for(var i in thisOplModel.r){
     ofile.writeln("d["+i+"+"]="+thisOplModel.d[i]]);
  }
  ofile.writeln("Optimal objective value="+cplex.getObjValue());
  ofile.writeln("Optimal variable values:");
  for(i in thisOplModel.r){
     ofile.writeln("x["+i+"]="+thisOplModel.x[i]);
  }
  ofile.close();
}

Thank you for any help!

Solution

  • If x is a 4D array instead of:

    for(i in thisOplModel.r){
     ofile.writeln("x["+i+"]="+thisOplModel.x[i]);
  }

    you could directly write:

    ofile.writeln("x="+thisOplModel.x);
