Y. Ma,V. Cherkassky class of problems can be attacked by this method. Thus with our approach, . on planar graphs is solved in time . and . is solved in time .. The proof of these results is based on complicated combinatorial arguments that make strong use of results derived by the Graph Minors Theory. In particular we
