The success of interior point algorithms for large-scale linear programming has prompted researchers to develop these algorithms to the semidefinite programming (SDP) case. In this paper, we extend Roos’s projective method for linear programming to SDP. The method is path-following and based on the useof a multiplicative barrier function. The iteration bound depends on the choice ofthe exponent μ in the numerator of the barrier function. The analysis in this paper resembles the one of the approximate center method for linear programming, as proposed by Rocs and Vial [14].展开更多
