The chinese postman problem

網頁2016年4月24日 · The Chinese postman problem, also known as the route inspection problem, is to find a circuit in a connected, undirected graph that visits each edge at least once. Additionally, a correct solution minimizes the total cost of the circuit. If all vertices of the graph have even degree, then the optimal solution is the Euler circuit of the graph. 網頁The Chinese postman problem is based on starting from a certain start point and to generate the shortest route with the condition that each point on the route is stopped at once at least one time (Ahuja, Magnatni, &Orlin, 1993). In addition to handling arcs
