Kroegentocht voor wiskundigen


Mathematicians have calculated the shortest distance to visit just about every pub in the UK.

Having a pint in each would take an estimated three years and involve travelling a total distance between 24,727 pubs of 28,270 miles – more than going round the world.

The route has been calculated by William Cook and a team of researchers at the University of Waterloo in Ontario, Canada.

It has broken the record for being the longest single road route ever worked out.

Cook was attempting to solve a conundrum known as the Travelling Salesman Problem (TSP) in which researchers try to calculate shortest possible routes in all sorts of environments.
