A note on Burer's copositive representation of mixed-binary QPs
In an important paper, Burer [2] recently showed how to reformulate general mixed-binary quadratic optimization problems (QPs) into copositive programs where a linear functional i...

Image segmentation by convex quadratic programming
A quadratic programming formulation for multiclass image segmentation is investigated. It is proved that, in the convex case, the non-negativity constraint on the recent reported ...

On the facet-to-facet property of solutions to convex parametric quadratic programs
In some of the recently-developed algorithms for convex parametric quadratic programs it is implicitly assumed that the intersection of the closures of two adjacent critical regio...

On the gap between the quadratic integer programming problem and its semidefinite relaxation
Consider the semidefinite relaxation (SDR) of the quadratic integer program (QIP): := maxx{-1,1}n xT Qx minD-Q 0 trace(D) =:

Instance similarity and the effectiveness of case injection in a genetic algorithm for binary quadratic programming
When an evolutionary algorithm addresses a sequence of instances of the same problem, it can seed its population with solutions that it found for previous instances. This techniqu...
