Simplex method notes
Webb8 The Two-Phase Simplex Method The LP we solved in the previous lecture allowed us to find an initial BFS very easily. In cases where such an obvious candidate for an initial BFS does not exist, we can solve a different LP to find an initial BFS. We will refer to this as phase I. In phase II we then proceed as in the previous lecture. WebbSearch direction Simplex method!
