Quadratic Convex Reformulations for Semicontinuous Quadratic Programming [PDF]
Summary: We consider in this paper a class of semicontinuous quadratic programming problems, which arises in many real-world applications such as production planning, portfolio selection, and subset selection in regression. We build upon the idea of the quadratic convex reformulation approach, i.e., adding to the original objective function an ...

On convex relaxations for quadratically constrained quadratic programming [PDF]
A quadratically constrained (possibly non-convex) quadratic programming problem is considered. The efficiency, for this problem, of several known convex underestimating methods is analyzed. The underestimates, obtained by means of the considered methods, are ranked according to their tightness.

An algorithm for indefinite quadratic programming with convex constraints [PDF]
The authors present a new branch-and-bound method for solving the following problem: \[ \min(f(x,y)=p^ T x+x^ T My+q^ T y: (x,y)\in S), \] where \(S\subset R^ n\times R^ m\) is a closed convex non-empty set, \(p\in R^ n\) and \(q\in R^ m\) are given vectors and \(M\) is a given \(n\times m\) matrix.

Convex Quadratic Sets and the Complexity of Mixed Integer Convex Quadratic Programming
In pure integer linear programming it is often desirable to work with polyhedra that are full-dimensional, and it is well known that it is possible to reduce any polyhedron to a full-dimensional one in polynomial time. More precisely, using the Hermite normal form, it is possible to map a non full-dimensional polyhedron to a full-dimensional isomorphic
