Webbartificial variables. In order for the initial basis to be useful, it needs to be in terms of the original variables. We divide the simplex method into two phases. Phase 1 finds an initial feasible basic solution. Phase 2 finds an optimal feasible basic solution. The steps of phase 1 and 2 are identical. Webb3.2 The two-phase dual simplex method This is also something we can do in phase one of the two-phase simplex method. Here, our goal is just to nd a basic feasible solution to begin with, and then we can continue with the simplex method as usual. Instead of adding arti cial variables to nd a basic feasible solution, we can use the dual simplex

If LP is a min (max) problem add for each artificial variable 𝑀𝑎𝑖 (−𝑀𝑎𝑖 ) to the objective function. Step 5. Because each artificial variable will be the starting basis, each must be eliminated from row 0 before beginning simplex. It is optimal if all the artificial variables are ...

WebbAs any other variable, artificial variables are included in the objective function but the value attached to them creates another problem. In minimisation problems, since the objective is to find the lowest cost possible, a very large value is allocated to artificial variables. This value is denoted by M where M is a very large positive value.
