Solving the submodel

Provides the syntax.

1. Write the writeln statement:

         if ( subCplex.solve() &&
              subCplex.getObjValue() <= -RC_EPS) {
           writeln();
           writeln("SUB OBJECTIVE: ",subCplex.getObjValue());
         } else {
           writeln("No new good pattern, stop.");
              subData.end();
           subOpl.end();         
           break;
         }
   

2. Check the objective:

         if (subCplex.getObjValue() > -RC_EPS) { 
           break;
         }
   

If the objective is not favorable, you stop the process. Remember that the objective represents the reduced cost of the new candidate pattern.
