Good morning/afternoon/evening everybody; I have a question about the edges' id.
In particular, I can't understand what happens to edges' id when I add/remove egdes and when I transform an undirected graph to a directed (MUTUAL) one. In the first case, I suppose that, if you have a graph with N edges indexed from 0 to N-1 and you add the (N+1)th edge, it will be indexed as N. Am I right or am I not? Then, what happens when I remove an edge? there will be a gap or a re-indexing? And, in particular: let us suppose i have an undirected graph with N edges, indexed from 0 to N-1. I want to transform the graph into a directed one with mutual edges, i.e. the number of edges will be doubled. What happens to the ids? Let us suppose I consider the edge indexed as j; the mutual edge will be j+1 (and thus, the old edges will be re-indexed) or N+j? Or something else? Thank you for your help!
