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. Webb7 juli 2010 · The downhill simplex algorithm was invented by Nelder and Mead [1].
