A few variants of the Chinese Postman Problem have been studied and shown to be NP-complete. The windy postman problem is a variant of the route inspection problem in which the input is an undirected graph, but where each edge may have a different cost for traversing it in one direction than for traversing … See more 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 … See more Various combinatorial problems have been reduced to the Chinese Postman Problem, including finding a maximum cut in a planar graph and a minimum-mean length circuit in an undirected graph. See more • Weisstein, Eric W., "Chinese Postman Problem", MathWorld • Media related to Route inspection problem at Wikimedia Commons See more The undirected route inspection problem can be solved in polynomial time by an algorithm based on the concept of a T-join. Let T be a set of … See more On a directed graph, the same general ideas apply, but different techniques must be used. If the directed graph is Eulerian, one need only find … See more • Travelling salesman problem • Arc routing • Mixed Chinese postman problem See more WebSolving the Chinese Postman Problem is quite simple conceptually: Find all nodes with odd degree (very easy). (Find all trail intersections where the number of trails touching that intersection is an odd number) Add edges to the graph such that all nodes of odd degree are made even. These added edges must be duplicates from the original graph ...
