Chinese postman or route inspection

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. WebYou've probably heard of the Travelling Salesman Problem which amounts to finding the shortest route (say, roads) that connects a set of nodes (say, cities). Although lesser known, the Chinese Postman Problem (CPP), also referred to as the Route Inspection or Arc Routing problem, is quite similar. The objective of the CPP is to find the ...
