The major part of this chapter is devoted to a network optimization problem, namely to findi

In the present chapter, we mainly treat algorithmic questions concerning .-connectivity and strong connectivity. To this end, we introduce a further important strategy for searching graphs and digraphs (besides BFS), namely .. In addition, we pr

As an aside, we explain the relationship between colorings and partial orderings, and briefly discuss perfect graphs. Moreover, we consider edge colorings of Cayley graphs; these are graphs which are defined usin

For example, quite often there are also lower bounds on the capacities of the edges given, or a cost function on the edges. To solve this kind of problem, it makes sense to remove t

On the one hand, we will consider the case where all edges may be built with the same cost, and where we are looking for an undirected network with lower bounds on the maximal values of a flow between any two v
