WebbComplete example of the two-phase method in 3x3 dimensions: ... we have k=1 and index i=1 Pivot element is on a ik = a 11 We do an iteration of the simplex algorithm in the following way; 1) If the row is that of the pivot element, we simply divide each element by the pivot element ... WebbOne such method is called the simplex method, developed by George Dantzig in 1946. It provides us with a systematic way of examining the vertices of the feasible region to determine the optimal value of the objective function. We introduce this method with an …

Webb8 The Two-Phase Simplex Method The LP we solved in the previous lecture allowed us to find an initial BFS very easily. In cases where such an obvious candidate for an initial BFS does not exist, we can solve a different LP to find an initial BFS. We will refer to this as phase I. In phase II we then proceed as in the previous lecture. http://www.math.chalmers.se/Math/Grundutb/CTH/tma947/1617/lectures/lecture9.pdf
