WebbIn the simplex method, we go from one basic solution to the next by pivoting in such a way that the resulting value of $p$ keeps going up. When it cannot go any higher, we are done! The secret of the method is how we choose the pivot in order to make the value of $p$ increase. Here are the rules for selecting the pivot at any stage. 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.
