Abstract
We study the semidefinite programming problem (SDP), i.e the problem of optimization of a linear functionof a symmetric matrix subject to linear equality constraints and the additional condition that the matrixbe positive semidefinite. First we review the classical cone duality as specialized to SDP. Next we presentan interior point algorithm which converges to the optimal solution in polynomial time. The approach is adirect extension of Ye's projective method for linear programming. We...
