Dec 01, 1973 · The solution of the Chinese postman problem using matching theory is given. The convex hull of integer solutions is described as a linear programming polyhedron. This polyhedron is used to show that a good algorithm gives an optimum solution. The algorithm is a specialization of the more generalb-matching blossom algorithm. Algorithms for finding Euler tours and related problems are …Cited by: 1209

Therefore the shortest postman tour has a weight of 75. Application 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 ...

Route Inspection Algorithm - Chinese Postman Problem. In 1962, Kuan Mei-Koa, a Chinese mathematician, came up with what later became known as Chinese Postman Problem. He was interested in a local postman, delivering mail to a number of streets in his locality in such a way that the total distance walked by the postman could be kept to a minimum ...
