Webb26 sep. 2024 · The artificial variable technique is a device to get the starting basic feasible solution, so that simplex procedure may be adopted as usual until the optimal solution is obtained. To solve such LPP there are two methods. (i) The Big M Method or Method of Penalties. (ii) The Two-phase Simplex Method.
