[igraph] how to increment reciprocity

[Simone Gabbriellini]

Dear List,

I am trying to write a routine that adds edges to a graph in order to
increment  the reciprocity of the graph...

my code, but it doesn't work well, is something like:

for node in g.vs:
        nei_vertex = g.neighbors(node, type="in")

        if (g.vs[node]["experience"] >= 20) and (g.vs[node]["experience"] <= 
60):
                selectedNodeId = self.pickupEQ(nei_vertex)
                self.do_link(node, selectedNodeId)


def pickupEQ(self, nei_vertex):
        selectedNodeId = random.sample(nei_vertex, 1)[0]
        return selectedNodeId
                
# costruisci un link con quel nodo, oppure aggiungi 1 al peso del link esistente
def do_link(self, node, selectedNodeId):
        try:
                eid = self.SNA.network.get_eid(node, selectedNodeId)            
        
        except:
                max_edge_id = self.SNA.network.ecount()
                self.SNA.network.add_edges((node, selectedNodeId))
                self.SNA.network.es[max_edge_id]["color"] = "orange"
                self.SNA.network.es[max_edge_id]["weight"] = 1
        else:
                self.SNA.network.es[eid]["weight"] += 1


could there be better ways to accomplish my task?

best regards,
simone
