Abstract
Maximum Edge Disjoint Paths is a classical NP-hard problem of finding a maximum-size subset from a given set of k terminal pairs that can be routed via edge-disjoint paths. One of the big open problems in approximation algorithms is to close the gap between the best known approximation upper and lower bound.

In this talk, I introduce the problem and present new approximation algorithms (ESA 2016) that strengthen best-known results. They provide new bounds formulated in terms of the feedback vertex set number r of a graph, which measures its vertex deletion distance to a forest.
