Excellent story in the Washington Post about the complications of route optimization for snowplows. It includes the most famous origin story in mathematics – Euler realizing he couldn’t cross the seven bridges of Königsberg just once and thus founding graph theory and topology – and a good discussion about balancing human and algorithmic decision making.
The story is here.
