Mixed-Integer Nonconvex Quadratic Optimization Relaxations and Performance Analysis
Abstract
The project addresses a fundamental question regarding the mixed integer quadratic programs (MIQP): how to find a provably high quality approximate solution efficiently? Given the nonconvex nature of the problem, two relaxation approaches are considered: one is based on convex semidefinite relaxation (SDR), while the other is based on quasic on quasi-convex relaxations. For SDR, a new probabilistic rounding procedure is proposed to account for both the binary and continuous variables. The performance of this rounding procedure is shown to deliver a constant factor approximation ratio for a class of the mixed integer quadratic optimization problems.
