“…If the performance guarantee of this algorithm is improved (as it has been for certain classes of graphs such as planar graphs or graphs with excluded minors [Park and Phillips 1993;Rao 1992;Klein et al 1993] and dense graphs [Arora et al 1995]), then it will be possible to derive corresponding improvements in the performance guarantees in the other algorithms described in the section.…”

“…Park and Phillips [18] devise a pseudo-polynomial time algorithm for solving (exactly) the minimum quotient edgecut problem (improving over a constant factor approximation in [19,20]). Klein, Plotkin and Rao [11] give a constant factor approximation for the directed version of this problem.…”

“…The algorithms proceed by searching for simple cycles in the dual of the planar graph. In particular, Park and Phillips [18] define a cost and weight for each edge in the dual graph such that the cost of any simple cycle in the dual graph is equal to the cost of the corresponding cut in the input graph, and the weight of the cycle corresponds to the weight that the cut separates. Then, they can modify methods for finding minimum mean cycle, due to [10], to find the best such cycle.…”
