Dualer Simplex: Erklärung, Berechnung und Beispiele

Web8. In general, if the primal problem is too difficult to solve (i.e. put into standard form and use the Simplex method), then likely it is easier to solve the dual problem. If you have to add a lot of artificial variables for solving the primal, then you are probably better off writing the dual of the LP and solving it using the Dual Simplex ... http://www-personal.umich.edu/~murty/510/510slides7.pdf WebHier klicken zum Ausklappen Primaler Simplex-Algorithmus: Jedes Tableau ist zulässig, jedoch ist nur das letzte optimal.
