Starting in 1952, the simplex method was programmed for … WebbThis is in analogy with the standard pivoting rule. Recall that for the (usual) Simplex Method we can pick the entering variable to be any of the non-basic variables whose coefficient in the \(z\)-row is positive (all of those choices serve to increase the objective function), but specific pivoting rules tell you exactly which one to pick: the standard rule …
