• #### Bound constrained quadratic programming via piecewise quadratic functions ﻿

(Springer-Verlag, 1999)
We consider the strictly convex quadratic programming problem with bounded variables. A dual problem is derived using Lagrange duality. The dual problem is the minimization of an unconstrained, piecewise quadratic function. ...
• #### A finite continuation algorithm for bound constrained quadratic programming ﻿

(Society for Industrial and Applied Mathematics Publications, 1998)
The dual of the strictly convex quadratic programming problem with unit bounds is posed as a linear ℓ1 minimization problem with quadratic terms. A smooth approximation to the linear ℓ1 function is used to obtain a parametric ...
