So, recently, my Facebook feed has blown up with this image, and related stories about doctoral student Randy Olson at Michigan State University.  Mr. Olson has done work finding optimum Hamilton Circuits, a topic that I used to teach in my Discrete Math course, but on a much bigger scale!  Mr. Olson attempted to optimize a circuit visiting a major historical landmark in each state of the contiguous United States.   Click here to see the whole story!  This link also explains more of how he did it, using a computer-generated algorithm slightly different than those we used.

Discrete Math is used everywhere!!
