WebbIntroduction to the Simplex Algorithm - Microsoft WebbAbstract. The adaptation of the primal simplex method for solving minimum linear cost network flow problems is well known. We present a new data structure for storing the tree associated with a basis and introduce a new adaptive heuristic method for the pivot choice. The pivot choice is modified dynamically during the application of the algorithm.

http://www.scholarpedia.org/article/Nelder-Mead_algorithm 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.
