Hello Christian, I wrote bad the code in the mail, but in my class I update the variables in this way,
listVarMachines[i].update(*this, share, s.listVarMachines[i]); I'm initializing the stl-vectors that contain IntArgs in this way: listResources.push_back(IntArgs(size, anIntegerArray)); And the stl-vectors that contain IntVarArray in this way: for the machines: listaVarMachines.push_back(IntVarArray(*this, size, anIntSet)); for the times of the tasks: listVarTStart.push_back(IntVarArray(*this, size, 0, MAX-MAKESPAN)); MAX-MAKESPAN is an int. Take values > 500, it depends of the problem to solve. Thanks a lot for helping me.
