Example: NEAT in directed networks. Left: directed network consisting of 8 nodes connected by 15 arrows. Set A contains nodes 1 and 4 (red) and set B nodes 3, 5 and 7 (orange). Right: bipartite representation of the same network: it can be observed that n AB =2, o A =5, i B =4 and i V =15. It follows that μ 0=1.07 and p=0.48
