The red dots denote the type frequencies of the examples in Fig. 6. (b) The two parameters τ and κ yield a nice orthogonal coordinate system for our region of interest. WebbIt enabled solutions of linear programming problems that were beyond the capabilities of the simplex method. In contrast to the simplex method, it reaches a best solution by traversing the interior of the feasible region. The method can be generalized to convex programming based on a self-concordant barrier function used to encode the convex set.
