Detailed Description

Implements the base NLP interface using a Thyra::ModelEvaluator object.

The nonlinear program is mapped as follows:

    min     f(x)
    s.t.    c(x) = 0
            xL <= x <= xu


        x = [ model.x        ]
            [ model.p(p_idx) ]

        f(x) = model.g(g_idx)

        c(x) = model.f()


where p_idx > 0 and g_idx > 0 are some indexes that specificy the indepenent variables and the objective function.

In addition, the client can also override the bounds on model.x and model.p(p_idx) defined in the object model.

The current implementation of this class does not allow the use of any of the auxiliary functions model.g() as undecomposed equality constraints or extra general inequality constraints. This type of functionality can be added when it is needed (just ask for it).

model[in] NonlinearProblem that defines all of the functions and variables.
p_idx[in] Index of the subset of parameter vectors to use as the independent variables. If p_idx < 0, then no extra parameters are added.
g_idx[in] Index of the subset of auxiliary response functions to use as the objective function. Note, only the first element model.g(g_idx)(1) will be used as the objective function value.
model_xL[in] Pointer to upper bounds for the state variables model.x. If NULL then the default supplied in model->get_x_lower_bounds() will be used.
model_xU[in] Pointer to upper bounds for the state variables x. If NULL then the default supplied in model->get_x_upper_bounds() will be used.
model_x0[in] Pointer to initial guess for the state variables x. If NULL the the default supplied in model->get_x_init() will be used.
