I Below is a java applet that will present a set of linear programming problems for you to solve. After correctly solving a problem, the applet will immediately give you a new one. Each problem must be solved using the two-phase Simplex Method with artificial variable x0 . Any attempt to make an incorrect pivot will be rejected but your score will be increased by one.
Low scores are better than high scores.
You must click on the appropriate row of the artificial variable column x0 to make the first pivot, generating a feasible dictionary for the auxiliary problem, eliminating all the purple colors in the left column and generating yellow colors in the second row, highlighting the possible entering variables for the auxiliary problem. If the original problem is infeasible, you should be able to reduce x0 to zero and make the yellow colors all disappear, and then continue with Phase II as usual. The set of linear programming problems to be solved is determined by specifying the number of rows, the number of columns, the seed, and the number of problems in the set. Your instructor will tell you what values to use for these fields. Make sure that you enter exactly what your instructor tells you for otherwise you will be doing the wrong set of problems and it will be impossible to fairly evaluate your performance.
