The theory of self-concordance, initiated by Nesterov and Nemirovskii, has become very popular in recent years. In this paper an ln ν reduction of the complexity is given for finding the analytical center for a ν-self-concordant barrier. This center-finding step is a crucial one in the primal self-concordant barrier method.
