Detailed Description

The classes define the interface for qp solvers to be compatible with ConicBundle::UnconstrainedGroundset and ConicBundle::LPGroundset. Solvers obeying these requirements may be installed by ConicBundle::MatrixCBSolver::set_qp_solver().

The model description consists of a cutting model and a quadratic prox term. The cutting model needs to be collected via the properties of a QPModelDataPointer, see Interface for qp solver dependent model descriptions. Default quadratic proxterms are passed to the solver in the form of a ConicBundle::BundleProxObject, see Quadratic Proximal Terms, but the unspecific QPSolverProxObject opens some room for other contexts. Likewise the unspecified QPSolverParameterObject only serves as a place holder for a class specificying the paraemers of the current solver.

Implementations are ConicBundle::QPSolver for general a general ConicBundle::LPGroundset and ConicBundle::UQPSolver (see Internal QP Solver for linearly constrained groundsets) for ConicBundle::UnconstrainedGroundset as well as special prox combinations with a box constrained ConicBundle::LPGroundset.
