This article considers feasible long-step primal-dual path-following methods for semidefinite programming based on Newton directions associated with central path equations of the form Phi ( PXPT , P-T SP-1) - nu I = 0, where the map Phi and the nonsingular matrix P satisfy several key properties. An iteration-complexity bound for the long-step method is derived in terms of an upper bound on a certain scaled norm of the second derivative of Phi. As a consequence of our general framework, we derive polynomial iteration-complexity bounds for long-step algorithms based on the following four maps: Phi(X, S) = (XS + SX) /2 , Phi(X,S) = L-x(T) SLx , Phi(X,S) = X-1/2 S X-1/2, and Phi (X , S) = W-1/2 XSW-1/2 , where L-x is the lower Cholesky factor of X and W is the unique symmetric matrix satisfying S = WXW . |
