The postman problem

Webb1 sep. 1984 · The problem The so-called `windy postman problem' was proposed by E. Minieka in [I]. The problem is: "Let G = (V, E) be a connected undirected graph, such that for every e e E, e= (x, y), the distance from x to y can be different from the distance from y to x. Find a shortest postman route for graph G". http://www.suffolkmaths.co.uk/pages/Maths%20Projects/Projects/Topology%20and%20Graph%20Theory/Chinese%20Postman%20Problem.pdf
