WebThen R correspondsto a postman walk W for N with length(W) = length(R) = w(N ). Hence N has a postman walk of length k. 8.7 Corollary The minimum length of a postman walk of N is equal to the minimum weight of an Eulerian extension of N. Proof Take k as small as possible in Lemma 8.6 We will solve the Chinese Postman problem for a network N by ... 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.
