Last week, Tracy Staedter from Discovery News proposed an interesting idea to me: Why not use the same algorithm from my Where’s Waldo article to compute the optimal road trip across every state in the U.S.? Visiting every U.S. state has long been on my bucket list, so I jumped on the opportunity.

The travelling salesman problem (TSP) asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city and returns to the origin city?"It is an NP-hard problem in combinatorial optimization, important in operations research and theoretical computer science.

The (non-balanced) 2-period TSP may be viewed as a particular case of the Period Traveling Salesman Problem (PTSP) [5]. This last problem generalizes the TSP by extending the planning period to p days.

In computer science, artificial intelligence, and mathematical optimization, a heuristic (from Greek εὑρίσκω "I find, discover") is a technique designed for solving a problem more quickly when classic methods are too slow, or for finding an approximate solution when classic methods fail to find any exact solution. This is achieved by trading optimality, completeness, accuracy, or.
