From this SDP we obtain a primal-dual pair of SDP relaxations ... we obtain the relaxation. If the solution Xhas rank 1, then we have solved the original problem. Otherwise, rounding schemes to ... Webthe new QP relaxation bound is as tight as possible. The bound is equal to the value of the SDP relaxation of the QPCC, provided a constraint quali cation holds. This is also the continuation of the scheme of adding yTDw, where D is a nonnegative diagonal matrix, to the QPCC objective function to render

WebThe main features of the algorithm are the following: (1) the two variables are updated by solving a subproblem that, although nonconvex, can be analytically solved; (2) the adopted selection rule... WebWe show that a semideflnite programming (SDP) relaxation for this noncon- vex quadratically constrained quadratic program (QP) provides anO(m2) approxima- tion in the real case, and anO(m) approximation in the complex case. Moreover, we show that these bounds are tight up to a constant factor.
