Title: Lexicographic Flow
Authors: Kozen, Dexter
Keywords: flow
Issue Date: 25-Jun-2009
Abstract: The lexicographic flow problem is a flow problem in which the edges are assigned priorities, and we wish to find a flow that is lexicographically maximum with respect to the priority assignment. The problem is reducible to a weighted flow problem, but we show that exponentially large weights are necessary in general. We then give an efficient direct algorithm that does not use weights.
