S. Habibi (Birmingham Uni) An interior-point method for Lasserre relaxations of binary quadratic ...
03.04.2023 16:00-17:00
The aim of this presentation is to solve linear semidefinite programs arising from Lasserre relaxations of binary quadratic optimization problems. For this, we use an interior point method with a preconditioned conjugate gradient method to solve the linear systems. The preconditioner utilizes the low-rank structure of the solution of the relaxations. In order to fully utilize this, we re-write the moment relaxations. To treat the arising linear equality constraints, we use an $\ell_1$-penalty approach within the interior-point solver. The efficiency is demonstrated by numerical experiments and comparison with a state-of-the-art semidefinite solver.
