http://www.phpsimplex.com/en/simplex_method_example.htm 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.
