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. WebApplication of Chinese Postman Problem The practical example is planning of bus routing. In order to save the cost on the fuel, the bus company have modelled the bus stop as the vertix and the road as the edge in the bus route, then using the graph theory to obtain the optimal route that can meet the target of using the minimal fuel but across ...
