(25 points) Linearize the quadratic assignment formulation for Quadratic Assignment Formulation of the TSP There are an enormous number of subtour elmination constraints for a TSP on even a modest number of points. That is why it is sometimes easier-especially in developing heuristic procedures of Chapter 15to deal with a TSP formulation having simpler constraints. We can accomplish this, at the cost of making the objective function non- linear, by formulating the TSP as a quadratic assignment (QAP) model 11.16. Think of the tour as a sequence or permutation of the points to be visited. Decision variables in the OAP form assign sequence positions k to points is that is. fi if kth point visited is i 10 otherwise For example, the illustrative route of Figure 11.4 has V1.1 - Y23 F Y36 = 745 = Y5.4 = 76.8 179 18,10 V9,7 = V10.2 1 when viewed as starting at hole 1. In terms of these variables, either the symmetric or the asymmetric case can be formulated as an INLP. Give the full linearized model.
