Comment:

 {{{hessian_constant}}} refers to the Hessian of the Lagrangian function,
 which is not constant if you have quadratic (or other kind of nonlinear)
 constraints.

 That is, {{{hessian_constant}}} should be set only for models with linear
 constraints and at most quadratic objective functions.
