"WebHere, we’d have to use the two-phase simplex method to nd a basic feasible solution for the primal. In principle, whenever we have a dual feasible tableau, we can use the formula c B TA 1 B to nd a dual feasible solution, but we don’t always want to. For the tableau above, the dual feasible solution is (0;0;0). 2 The dual simplex method " - Two-phase simplex method solved examples
