(notice the use of the upper case in Min to denote a problem in contrast to min which denotes minimum when applicable). A vector x satisfying (3.2) is called a feasible solution of (3.3). A problem (3.3) having a feasible solution is said to be feasible, and infeasible in the opposite case. Hence, the problem (3.3) is feasible if and only if the system Ax = b is feasible in the terminology of Section 2.4. For a given linear program (3.3) we introduce the value
