\begin{ccRefConcept}{NonnegativeLinearProgram}

\ccDefinition
A model of \ccRefName\ describes a linear program of the form
\input{QP_solver_ref/_nlp_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.
