A coordinate ascent method for solving semidefinite relaxations of non-convex quadratic integer programs
Christoph Buchheim, Maribel Montenegro, Angelika Wiegele
We present a coordinate ascent method for a class of semidefinite programming problems that arise in non-convex quadratic integer optimization. These semidefinite programs are char…
Using a conic bundle method to accelerate both phases of a quadratic convex reformulation
Alain Billionnet, Sourour Elloumi, Amélie Lambert +1
We present algorithm MIQCR-CB that is an advancement of method MIQCR~(Billionnet, Elloumi and Lambert, 2012). MIQCR is a method for solving mixed-integer quadratic programs and wor…
Exact Solution Methods for the -item Quadratic Knapsack Problem
Lucas Létocart, Angelika Wiegele
The purpose of this paper is to solve the 0-1 -item quadratic knapsack problem , a problem of maximizing a quadratic function subject to two linear constraints. We propo…
