In the first section, we created a graph of the Königsberg bridges and asked whether it was possible to walk across every bridge once. Because Euler first studied this question, these types of paths are named after him. 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 closed walk that covers every edge once), that circuit is an optimal solution. Otherwise, the optimization problem is to find the smallest number of graph edges to duplicate (or the subs… josh morrison 17 dreamed ofWebThe (Chinese) Postman Problem, also called Postman Tour or Route Inspection Problem, is a famous problem in Graph Theory: The postman's job is to deliver all of the town's mail using the shortest route … josh morrissey capfriendly
