Problem 2 Consider the following integer programming (IP) problem maximize c'x subject to Ax g b x Z 0 x : integer, where A, b and c are all composed of positive integers. Let x0 its Optimal solution. Consider now the LP relaxation and let x1 its optimal solution. (a) Show that [x1] is a feasible solution of IP. (b) Show that the cost of [x1] can be no further from the optimal IP cost than 2?:1 0
