In this paper we consider a problem related to questions of optimal circuit layout: Given a graph or network, how can we embed it in a planar surface so as to minimize the number of edge-crossings? We show that this problem is NP-complete, and hence there is not likely to be any efficient way to design an optimal embedding.
