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 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 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 an Euler cycle. If it is not, one must find T-joins, which in this case entails finding paths from vertices with an in- 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 vertices in a graph. An edge set J is called a T-join if the collection of vertices that have an odd number of incident … See more 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 … See more • Travelling salesman problem • Arc routing • Mixed Chinese postman problem See more http://brooksandrew.github.io/simpleblog/articles/intro-to-graph-optimization-solving-cpp/

Solving the Chinese Postman Problem - DZone WebNov 1, 2024 · This paper presents a mathematical formulation and a heuristic approach for a new variant of the Hierarchical Chinese Postman Problem (HCPP). Indeed, we introduce the concept of periodicity, and we define and solve, for the first time, the Periodic-HCPP, denoted as P-HCPP.
