WebThe Chinese postman problem is interesting because it is a simple problem with wide application, but for which there is no simple algorithm. The known code for it is always … WebThe mixed Chinese postman problem (MCPP or MCP) is the search for the shortest traversal of a graph with a set of vertices V, a set of undirected edges E with positive rational weights, and a set of directed arcs A with positive rational weights that covers each edge or arc at least once at minimal cost. The problem has been proven to be NP-complete by …

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.

Chinese Postman Problem Given a connected graph, find a minimal length circuit (or path) traversing all edges of the graph. If the graph has an Euler circuit (or path), it is a minimal length circuit (or path) traversing the entire graph. Euler circuits and paths provide the most efficient means to traverse all edges of ... WebThe edges have varying weights and can be traveled in either direction and as many times as required. I am trying to determine the route that minimises the total weight. As I … northern gateway depot
