Detailed Description

General (and flexible) implementation class for a QPSchur QP problem.

The basic idea of this class is to just build the QP from its various components in a way that is easy and flexible for the client. The class will also do consistency testing if asked to.

const MatrixSymOp &  G,

size_type  n_R,

Initialize.

The pointers and references to the objects pointed to by the arguments to this function must not be modified by the caller. Copies of these objects are not made internally so these objects must remain valid while this object is in use.

If the sizes of the arguments do not match up or some consistency test fails then exceptions may be thrown with (hopefully) helpful messages.

Parameters:
g [in] vector (size n): objective gradient
G [in] matrix (size n x n): objective Hessian
A [in] matrix (size n x m): full rank equality constraints in Ko. If A==NULL then there are no equality constraints in Ko and m will be zero.
n_R [in] number of initially free variables
i_x_free [in] array (size n_R): i_x_free[l-1], l = 1...n_R defines the matrix Q_R as:
Q_R(:,l) = e(i_x_free[l-1]), l = 1...n_R
The ordering of these indices is significant. It is allowed for i_x_free == NULL in which case it will be considered to be identity.
i_x_fixed [in] array (size n_X = n - n_R): i_x_fixed[l-1], l = 1...n_X defines the matrix Q_X as:
Q_X(:,l) = e(i_x_fixed[l-1]), l = 1...n_X
The ordering of these indices is significant.
bnd_fixed [in] array (size n_X = n - n_R): bnd_fixed[l-1], l = 1...n_X defines the initial active set as:
{verbatim} / LOWER : b_X(l) = xL(i_x_fixed[l-1]) bnd_fixed[l-1] = | UPPER : b_X(l) = xU(i_x_fixed[l-1]) \ EQUALITY : b_X(l) = xL(i) = xU(i) (i = i_x_fixed[l-1]) {verbatim}
b_X [in] vector (size n_X = n - n_R): Initial varaible bounds (see bnd_fixed)
Ko [in] matrix (size (n_R+m) x (n_R+m)): Initial KKT matrix
fo [in] vector (size n_R + m): Initial KKT system rhs vector
constraints [in] Constraints object for the extra constraints cL_bar <= A_bar'*x <= cU_bar
out [out] If out!=NULL, then any warning or error messages will be printed here.
test_setup [in] If set to true, then consistency checks will be made on all the input arguments. The cost of the tests will not be too excessive in runtime or storge costs and do not completly validate everything
waring_tol [in] Warning tolerance for tests.
error_tol [in] Error tolerance for tests. If the relative error of any test exceeds this limit, then an error message will be printed to out (if out!=NULL) and then a runtime exception will be thrown.
print_all_warnings [in] If set to true, then any relative errors for tests that are above warning_tol will be printed to out (if out!= NULL) (O(n) output). Otherwise, if false, then only the number of violations and the maximum violation will be printed (O(1) output).
