WebIn this activity you will use the Chinese postman algorithm, (also called the Route Inspection Problem), to solve practical problems. It is called the Chinese postman algorithm because it was studied in 1962 by a Chinese mathematician called Kwan Mei-Ko, who was interested in minimising the total distance walked by a postman delivering mail. In graph theory, a branch of mathematics and computer science, Guan's route problem, the Chinese postman problem, postman tour or route inspection problem is to find a shortest closed path or circuit that visits every edge of an (connected) undirected graph. When the graph has an Eulerian circuit (a … See more The undirected route inspection problem can be solved in polynomial time by an algorithm based on the concept of a T-join.
