    Then the fundamental theorem of linear inequalities implies (for feasible problems) that for every vertex x * of the LP feasible region, there exists a set of d (or fewer) inequality constraints from the LP such that, when we treat those d constraints as equalities, the unique solution is x *. Thereby we can study these vertices by means of ...
