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 Webb2 as the basic variables is feasible. If not, try x 1 and x 3, and so on. But this reduces to the naive approach to linear programming, where we try all possible bases. (We don’t even know, necessarily, that this linear program has any feasible solutions.) The solution is the two-phase simplex method. In this method, we:

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.
