a. Identify a real world problem that you are familiar with that can be modeled as a TSP. State the problem. Set-up the distance matrix and solve it using the TSP model provided by the Lingo software. You need to define the number of cities and the distance matrix in the model and run it. Interpret the optimal solution and comment on the solution. Try to select a problem with 6 to 8 Tasks(cities). b. Run the TSP model with Blocks of Codes showing the heuristics removed. Interpret the new optimal solution. In this case, the solution will indicate a number of sub-tours (isolated tours) instead of one complete tour
