How to coupute the diameter of a graph with differents categries of relationships

[Youssef Mourchid]

Hello,

if can anyone help me to find a way to compute the diameter of a graph with different categories of edges i will be very thankful.

In my case my graph contains three categories of nodes (Person, speech, Time) and 6 relationships.

public double getDistancia(double latitude, double longitude, double latitudePto, double longitudePto){ double dlon, dlat, a, distancia; dlon = longitudePto - longitude; dlat = latitudePto - latitude; a = Math.pow(Math.sin(dlat/2),2) + Math.cos(latitude) * Math.cos(latitudePto) * Math.pow(Math.sin(dlon/2),2); distancia = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a)); return 6378140 * distancia; /* 6378140 is the radius of the Earth in meters*/ }

So what are you cypher query?

I have three nodes categories  (Person, Speech,TIME) and 6 different interactions (3 intra layer) and (3 inter layer), my problem is how to compute the diameter the hall graph (aggregation graph with the differents relationships)
