Solve the following LP problem using the Big M Method and the 2-Phase Method.
| min x1 + 4x2 + 2x3 |
| s.t. |
| x1 + x2 +x3 <= 2 |
| 2x1 + x2 <= 3 |
| 2x1 + 2x2 +3x3 >= 5 |
| x2,x3 >=0 |
The tutOR module for solving general LP problems using the 2-Phase method can be very useful here! However, observe that this module will not be available during the exam!
