What is LPP with Artificial Variables about?
The document describes solving a linear programming problem using the two-phase method. In phase I, the problem is transformed by introducing artificial variables and minimizing their sum to obtain a starting feasible basis. In phase II, the original objective function is optimized using this starting basis. The example problem is to minimize z=2x1+x2 subject to the constraints 3x1+x2≥9 and x1+x2≥6. Phase I yields a starting basis of x1=3/2, x2=9/2. Phase II then directly solves the original problem to find
