Analyticity of weighted central paths and error bounds for semidefinite programming
The purpose of this paper is two-fold. Firstly, we show that every Cholesky-based weighted central path for semi definite programming is analytic under strict complementarity. This result is applied to homogeneous cone programming to show that the central paths defined by the known class of optimal...

| Summary: | The purpose of this paper is two-fold. Firstly, we show that every Cholesky-based weighted central path for semi definite programming is analytic under strict complementarity. This result is applied to homogeneous cone programming to show that the central paths defined by the known class of optimal self-concordant barriers are analytic in the presence of strictly complementary solutions. Secondly, we consider a sequence of primal-dual solutions that lies within a prescribed neighborhood of the central path of a pair of primal-dual semi definite programming problems, and converges to the respective optimal faces. Under the additional assumption of strict complementarity, we derive two necessary and sufficient conditions for the sequence of primal-dual solutions to converge linearly with their duality gaps. |
