Detecting redundancy in optimization problems over intersection of ellipsoids

Research output: Contribution to journalArticlepeer-review


An ellipsoid within a system of ellipsoids is called redundant if it contains the intersection of all the other ellipsoids. We provide a semidefinite programming based method that uses the probabilistic Semidefinite Stand-and-Hit (SSH) algorithm for detecting redundant ellipsoids. This detects more complicated instances of redundancy than those found by the S-procedure.
