2 oct 2014 · The corresponding basic feasible solution is x = 0, z = b We use this to initialize the simplex algorithm The simplex method can be one of two possible results (note that the modified LP is never unbounded: since z ≥ 0, the objective function is bounded from below by 0 )

30 sept 2014 · Given a basic feasible solution x with corresponding basis B, we first compute the verifying y = (AT B)−1cB and the reduced cost ¯c = c − AT y
