WebbEdge lists. One simple way to represent a graph is just a list, or array, of E ∣E ∣ edges, which we call an edge list. To represent an edge, we just have an array of two vertex numbers, or an array of objects containing the vertex numbers of the vertices that the edges are incident on. If edges have weights, add either a third element to ... WebbThe answer was in this section of code: }else { DefaultWeightedEdge e = graph.addEdge (email.getSender (), email.getRecipients () [k]); graph.setEdgeWeight (e, 1); } It turns out that email.getSender () was in email.getRecipients () so the source and destination of the edge was the same i.e a loop. I solved the issue by doing a simple check ...
