Re: [Choco-users] maximize/minimize

[Hadrien C. <had...@em...>]

Hello,

The api concerning minization and maximization in not yet available on th=
e
Problem object. However, you can look at the following code which give yo=
u
an example of minimization. You only need to use the Solver object and
specify a couple of options :

public static void main(String[] args) {
    Problem pb =3D new Problem();
    IntVar fctObj =3D pb.makeBoundIntVar("objectif",-10,1000);
    IntVar v1 =3D pb.makeEnumIntVar("v1",1,10);
    IntVar v2 =3D pb.makeEnumIntVar("v2",-3,10);
    IntVar v3 =3D pb.makeEnumIntVar("v3",1,10);

    pb.post(pb.eq(pb.sum(new IntVar[]{v1,v2,v3}),fctObj));


    Solver solver =3D pb.getSolver();
    solver.setDoMaximize(false);
    solver.setObjective(fctObj);
    solver.setRestart(false);
    solver.setFirstSolution(true);
    solver.generateSearchSolver(pb);
    solver.launch();
  }

regards,

Hadrien and guillaume
