Integer Plane Multiflow Maximisation : Flow-Cut Gap and One-Quarter-Approximation

18 Mar 2020 Garg Naveen Kumar Nikhil Sebő András

In this paper, we bound the integrality gap and the approximation ratio for maximum plane multiflow problems and deduce bounds on the flow-cut-gap. Planarity means here that the union of the supply and demand graph is planar... (read more)
