http://xlinux.nist.gov/dads/HTML/chinesePostman.html 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 name "Chinese Postman problem" to Jack Edmonds when Edmonds was in Goldman's Operations Research group at the U.S. National Bureau of Standards (now NIST).

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 ...
