Primal barrier interior-point method

WebThe Interior Ellipsoid method of Ye and Tse [YT89] is a primal affine-scaling algorithm for convex quadratic programming in standard equality form. The primal affine scaling idea con-sists in minimizing the cost over a sequence of ellipsoids whose shape depends on the distance from the current interior feasible point to the faces of the WebPrimal-dual interior-point method • primal-dual central path equations • infeasible primal-dual method 15–1.
