Landschaftsplanerische Perspektivenhe previous chapters, we discuss these topics in this chapter. We will mostly consider (directed) cycles; in most cases the adjective ‘directed’ is omitted. Sometimes we will use oriented cycles, i.e. orientations of undirected cycles.

However, the topic is still a very active research field and there are challenging open problems such as deciding whether an .(.)algorithm. exists for the general maximum flow problem.

This chapter will mainly deal with global connectivity aspects. That is, the directed multigraph in question is .-(arc)-strong for some . ≥ 0, or we want to make it .-(arc)-strong by adding new arcs.

We briefly discuss the .-path problem for planar digraphs and indicate how to use the topological concept of planarity in proofs and algorithms for disjoint path problems in planar digraphs.
