In this paper the authors introduce a primal-dual affine scaling method. The method uses a search-direction obtained by minimizing the duality gap over a linearly transformed conic section. This direction neither coincides with known primal-dual affine scaling directions, nor does it fit in the general primal-dual method. The new method requires
