Unformatted text preview: the total number of streets that you have to visit. This can be formulated as a graph problem: given a connected graph G ( V,E ), nd a closed walk of minimum length that traverses every edge at least once. (a) Give a polynomial time algorithm that gives a closed walk of length at most 2  E  . (b) (Harder) Give a polynomial time algorithm that gives a closed walk of length at most  E  +  V  1. 1...
