Hello,

I am trying to generate several solution of a model varying a set of data every time. And I want to generate a .txt file for every iteration with a different file name where I'll export the solution. Can anyone suggest me any way of doing that??

Thanks in advance..!!

Hi,

an example is more clear than a long answer:

sub.mod

float maxOfx = ...;
    dvar float x;

    maximize x;
    subject to {
      x<=maxOfx;
    }

    execute
    {
    writeln("x= ",x);
    }
 

then

main {
      var source = new IloOplModelSource("sub.mod");
      var cplex = new IloCplex();
      var def = new IloOplModelDefinition(source);
     
     
     
      for(var k=1;k<=10;k++)
      {
      var opl = new IloOplModel(def,cplex);
        
      var data2= new IloOplDataElements();
      data2.maxOfx=k;
      opl.addDataSource(data2);
      opl.generate();

      if (cplex.solve()) {  
         opl.postProcess();
         writeln("OBJ = " + cplex.getObjValue());
         var f=new IloOplOutputFile("res"+k+".txt");
         f.writeln("OBJ = " + cplex.getObjValue());
         f.close();
      } else {
         writeln("No solution");
      }
     opl.end();
    }  
     
    }

will generate 10 files with results

regards
