title: What are real-world industry applications of TSP?
body: <p>Wikipedia says: </p>
  
  <blockquote>
    <p>The Travelling Salesman Problem has several applications even in its purest formulation, such
    as planning, logistics, and the manufacture of microchips.</p>
  </blockquote>
  
  <p>I would like to know more about the usage of TSP in different areas. Unfortunately, the search yields a lot of results on stating the problem and trying to solve it in a theoretical fashion only.</p>
  
  <p>I have also found this:</p>
  
  <blockquote>
    <p>In the Generalized Travelling Salesman Problem (GTSP), the aim is to
    determine a least cost Hamiltonian circuit or cycle through several
    clusters of vertices. It is shown that a wide variety of combinatorial
    optimization problems can be modelled as GTSPs. These problems include
    location-routeing problems, material flow system design, post-box
    collection, stochastic vehicle routeing and arc routeing.</p>
  </blockquote>
  
  <p>But again, it is too general.</p>
  
  <p>What examples of real world usage of the Travelling Salesman Problem and its solution(s) do you know?</p>
  
  <p>What could be done better if better solutions to the TSP existed?</p>
