Chinese postman algorithm
WebFile format: The first two lines give n (number of vertices) and m (number of edges). Each of the next m lines has a tuple (u, v, c) representing an edge, where u and v are the endpoints (0-based indexing) of the edge and c is its cost. WebThe Chinese Postman Problem • A similar problem is called Chinese Postman Problem (after the Chinese mathematician, Kwan Mei-Ko, who discovered it in early 1960's). • It is the problem that the Chinese Postman faces: he wishes to travel along every road in a city in order to deliver letters, with the least possible distance.
