\begin{ccRefConcept}{NonnegativeQuadraticProgram} \ccDefinition A model of \ccRefName\ describes a convex quadratic program of the form \input{QP_solver_ref/_nqp_description} The description is given by appropriate \emph{random-access} iterators over the program data, see below. The program therefore comes in \emph{dense} representation which includes zero entries. \ccHasModels \ccc{Quadratic_program}\\ \ccc{Quadratic_program_from_mps}\\ \ccc{Nonnegative_quadratic_program_from_iterators}\\ \ccTypes \input{QP_solver_ref/_abr_types.tex} \input{QP_solver_ref/_d_types.tex} \input{QP_solver_ref/_c_types.tex} \ccOperations \ccCreationVariable{qp} \input{QP_solver_ref/_nmabr_methods.tex} \input{QP_solver_ref/_d_methods.tex} \input{QP_solver_ref/_c_methods.tex} \ccRequirements The value types of all iterator types (nested iterator types, respectively, for \ccc{A_iterator} and \ccc{D_iterator}) must be convertible to some common \ccc{IntegralDomain} \ccc{ET}. \ccSeeAlso The models \ccc{Quadratic_program}\\ \ccc{Quadratic_program_from_mps}\\ \ccc{Nonnegative_quadratic_program_from_iterators} and the other concepts \ccc{QuadraticProgram}\\ \ccc{LinearProgram}\\ \ccc{NonnegativeLinearProgram} \end{ccRefConcept}
