Abstract: The educational testing problem is a convex non-smooth optimization problem. We recast the problem so that classical non-smooth optimization techniques such as the ellipsoid method can readily be applicable. Attention is paid to the Dikin's method where a special barrier function and interior ellipsoids for the feasible domain are explicitly formulated. The implementation is much easier than that in [8]. The convergence property is numerically demonstrated. (Update)
