The travelling salesman problem(TSP) involves finding the shortest route to visits each stop once before returning to the starting point. An obvious approach to solving the TSP is to determine all the possible routes and pick the shortest one. So why don’t people do this all the time? It turns out that this … See more The TSP may be formulated as an integer linear programming (ILP) model. In the following, we develop the well known Miller-Tucker-Zemlin (MTZ) formulation. Although it is not the … See more The next step is to enter the data. This means to provide a distance matrix (or cost matrix), which gives the pairwise distances between stops. For pedagogical and pratical … See more Scripting log Then, the optimal tour starting from stop 1 is 1 -> 12 -> 14 -> 3 -> 13 -> 11 -> 10 -> 2 -> 17 -> 9 -> 8 -> 5 -> 4 -> 16 -> 15 -> 7 -> 6 -> 1 Solutions Engine log Instead of 4 days brute-forcing, we solve it with … See more WebJan 8, 2024 · An implementation ( using cplex ) of the original formulation of Miller-Tucker-Zemlin for the TSP. c-plus-plus cplex tsp miller-tucker-zemlin Updated Apr 3, 2014; C++; li3939108 / ilpext Star 0.
