Recovery of the Analytic Center in Perturbed Quadratic Regions and Applications
Angel Sanchez (asanchezufrrj.br)
Abstract: We present results to recover an approximate analytic center when a sectional convex quadratic set is perturbed by a finite number of new quadratic inequalities. This kind of restarting may play an important role in some interior-point algorithms that successively refine the region where is the solution of the original problem.
Keywords: analytic center, quadratic regions, restarting, shifting
