    obj
  End Variables

  Equations
    obj = sin(x[1] + x[2]) + (x[1] - x[2])^2 - 1.5*x[1] + 2.5*x[2] + 1

    ! best known objective = (-1)*sqrt(3)/2 - Pi/3 = -1.913222954981036
    ! begin of best known solution
    ! x[1] = (-1)*Pi/3 + 1/2 = -0.5471975511965977
    ! x[2] = (-1)*Pi/3 - 1/2 = -1.547197551196598
    ! end of best known solution
