TY - JOUR A1 - Sagnol, Guillaume T1 - A class of Semidefinite Programs with rank-one solutions JF - Linear Algebra and its Applications N2 - We show that a class of semidefinite programs (SDP) admits a solution that is a positive semidefinite matrix of rank at most $r$, where $r$ is the rank of the matrix involved in the objective function of the SDP. The optimization problems of this class are semidefinite packing problems, which are the SDP analogs to vector packing problems. Of particular interest is the case in which our result guarantees the existence of a solution of rank one: we show that the computation of this solution actually reduces to a Second Order Cone Program (SOCP). We point out an application in statistics, in the optimal design of experiments. Y1 - 2011 U6 - https://doi.org/10.1016/j.laa.2011.03.027 VL - 435 IS - 6 SP - 1446 EP - 1463 ER -
