## A Long Step Primal-Dual Path Following Method for Semidefinite Programming

### Jianmin Jiang

In this paper, we consider an extension of the long step primal-dual path followin g method developed by Jansen et al. for linear programming to semidefinite programming. By extending the proximity measure and using the primal-dual logarithmic function as the merit function, we present an algorithm which finds an $\varepsilon$-optimal solut ion in at most $O(n|\ln \varepsilon |)$ iterations.
