But the present version of simplex method was developed by Geoge B. ) For maximization problems like this one the constraints can often be thought of as restrictions on the amount of resources available, and the objective can be thought of as profit. Alternatively, using the CSC: we notice that since X^ ^ 0, therefore, the second constraint in the dual problem must be binding, i. Consider this problem:. If the slack variable decreases then it results in an increased cost (because negative times negative results in a positive). Shadow price. Start studying OM 300 HW10 module B linear programming.
