Unformatted text preview: that there are no counterclockwise residual cycles in the residual graph G . 2. What price function would you use to get the same property as in (1), but with no clockwise residual cycles? 3. Use parts (1) and (2) to give a linear time algorithm that, given a ow assignment in G makes acyclic by removing all ow cycles in . That is, it produces another ow assignment s.t. (a) - is a circulation (b) for every arc a , (( a, 1)) (( a, 1)) (c) for any cycle C there is a dart d C s.t. ( d )...
