Question: The postman problem is the problem of finding a closed walk W: s?s (s the post office) in a graph G with edges (i, j)

The postman problem is the problem of finding a closed walk W: s?s (s the post office) in a graph G with edges (i, j) of length l_ij?> 0 such that every edge of G is traversed at least once and the length of W is minimum. Find a solution for the graph in Fig. 484 by inspection. (The problem is also called the Chinese postman problem since it was published in the journal Chinese Mathematics 1
