Mathematicians map shortest route between 25,000 UK pubs
A team of mathematicians has planned the shortest possible route between nearly 25,000 pubs across the UK, in what is being dubbed the 'world's longest pub crawl.' It took two years to plan the 45,495-kilometre tour. The project is an example of The Travelling Salesman Problem, which maps the shortest route between numerous locations before returning to the starting point.
