That is, when we’re solving a minimization problem, a dual feasible tableau is one with nonnegative reduced costs. When we’re solving a maximization problem, a dual feasible tableau is one with nonpositive reduced costs. For other choices of B, once we haven’t usually considered, the tableau can be dual feasible but
