Exploiting group symmetry in semidefinite programming relaxations of the quadratic assignment problem
We consider semidefinite programming relaxations of the quadratic assignment problem, and show how to exploit group symmetry in the problem data. Thus we are able to compute the b...

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) =:

Solving Large Scale Binary Quadratic Problems: Spectral Methods vs. Semidefinite Programming
In this paper we introduce two new methods for solving binary quadratic problems. While spectral relaxation methods have been the workhorse subroutine for a wide variety of comput...
