    In the absence of degeneracy, a pivot operation always results in a strict decrease in c T x. Therefore, if the problem is bounded, the revised simplex method must terminate at an optimal vertex after repeated pivot operations because there are only a finite number of vertices. [4] Select an index m < q ≤ n such that s q < 0 as the entering ...
