WebbThe Evolutionary Solving method is designed for these problems. You can use integer, binary, and alldifferent constraints on variables with all three Solving methods. However, these constraints make the problem non-convex and much harder to solve. With the Simplex LP Solving method, you can find a globally optimal solution given enough time ... 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.
