WebKwan's article referred to optimizing a postman's route, was written by a Chinese author, and appeared in a Chinese math journal. Based on this Alan J. Goldman suggested the … WebApr 12, 2012 · 1 Answer. Your variant is NP-hard by a reduction from, e.g., the 3-partition problem where all values are strictly between B/4 and B/2. It might be "solved" using some of the same methods as capacitated vehicle routing. You have to understand, though, that CPP is less a real problem than an excuse to study T-joins.

WebNov 21, 2014 · Presentation Transcript. 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 ... 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.
