For any integern, a modified transportation problem with 2n + 2 nodes is constructed which requires 2^{ n } + 2^{ n−2}−2 iterations using all but one of the most commonly used minimum cost flow algorithms.
As a result, the Edmonds—Karp Scaling Method [3] becomes the only known “good” (in the sense of Edmonds) algorithm for computing minimum cost flows.
